The DAC104S085 is packaged in 10pin SON and VSSOP packages. The 10-pin SON package makes the DAC104S085 the smallest QUAD DAC in its class. The on-chip output amplifier allows rail-to-rail output swing and the three wire serial interface operates at clock rates up to 40 MHz over the entire supply voltage range. Competitive devices are limited to 25-MHz clock rates at supply voltages in the 2.7-V to 3.6-V range. The serial interface is compatible with standard SPI, QSPI, MICROWIRE, and DSP interfaces. 1 * * * * * * * Qualified for Automotive Applications AEC-Q100 Qualified With the Following Results: - Device Temperature Grade 1: -40C to 125C Ambient Operating Temperature Ensured Monotonicity Low Power Operation Rail-to-Rail Voltage Output Power-On Reset to 0 V Simultaneous Output Updating Wide Power Supply Range (2.7 V to 5.5 V) Key Specifications - Resolution: 10 bits - INL: 2 LSB (Maximum) - DNL: +0.35 / -0.25 LSB (Maximum) - Settling Time: 6 s (Maximum) - Zero Code Error: 15 mV (Maximum) - Full-Scale Error: -0.75% FS (Maximum) - Typical Supply Power - Normal Mode: 1.1 mW (3 V), 2.5 mW (5 V) - Power Down: 0.3 W (3 V), 0.8 W (5 V) The reference for the DAC104S085 serves all four channels and can vary in voltage between 1 V and VA, providing the widest possible output dynamic range.

A power-down feature reduces power consumption to less than a microWatt with three different termination options. The low power consumption and small packages of the DAC104S085 make it an excellent choice for use in battery-operated equipment. The DAC104S085 is one of a family of pin-compatible DACs, including the 8-bit DAC084S085 and the 12-bit DAC124S085. The DAC104S085 operates over the extended industrial temperature range of -40C to +125C. 6 Pin Configuration and Functions DSC Package 10-Pin SON Top View VA 1 VOUTA 2 VOUTB 3 VOUTC 4 VOUTD 5 DGS Package 10-Pin VSSOP Top View 10 SCLK 9 SYNC SON 8 DIN 7 VREFIN VA 1 VOUTA 2 VOUTB VOUTC 6 GND VOUTD 10 SCLK 9 3 VSSOP 8 4 7 5 6 SYNC DIN VREFIN GND Pin Functions PIN NO.

Ground reference for all on-chip circuitry. 9 SYNC Digital Input Frame synchronization input for the data input. When this pin goes low, it enables the input shift register and data is transferred on the falling edges of SCLK. The DAC is updated on the 16th clock cycle unless SYNC is brought high before the 16th clock, in which case the rising edge of SYNC acts as an interrupt and the write sequence is ignored by the DAC. 10 SCLK Digital Input Serial Clock Input. Data is clocked into the input shift register on the falling edges of this pin. 11 PAD (SON only) Ground Exposed die attach pad can be connected to ground or left floating. Soldering the pad to the PCB offers optimal thermal performance and enhances package self-alignment during reflow.

These are stress ratings only, which do not imply functional operation of the device at these or any other conditions beyond those indicated under Recommended Operating Conditions. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability. All voltages are measured with respect to GND = 0 V, unless otherwise specified. If Military/Aerospace specified devices are required, please contact the TI Sales Office/Distributors for availability and specifications. When the input voltage at any pin exceeds 5.5 V or is less than GND, the current at that pin should be limited to 10 mA. The 20 mA maximum package input current rating limits the number of pins that can safely exceed the power supplies with an input current of 10 mA to two. The absolute maximum junction temperature (TJmax) for this device is 150C. The maximum allowable power dissipation is dictated by TJmax, the junction-to-ambient thermal resistance (JA), and the ambient temperature (TA), and can be calculated using the formula PDMAX = (TJmax - TA) / JA. The values for maximum power dissipation is reached only when the device is operated in a severe fault condition (that is, when input or output pins are driven beyond the operating ratings, or the power supply polarity is reversed). 7.2 ESD Ratings - DAC104S085 VALUE V(ESD) (1) (2) Electrostatic discharge Human-body model (HBM), per ANSI/ESDA/JEDEC JS-001 (1) (2) 2500 Machine model (MM) 250 UNIT V JEDEC document JEP155 states that 500-V HBM allows safe manufacturing with a standard ESD control process.

The reference voltage is externally applied at VREFIN and is shared by all four DACs. For simplicity, Figure 26 shows a single resistor string. This string consists of 1024 equal valued resistors with a switch at each junction of two resistors, plus a switch to ground. The code loaded into the DAC register determines which switch is closed, connecting the proper node to the amplifier. The input coding is straight binary with an ideal output voltage found in Equation 1: VOUTA,B,C,D = VREFIN x (D / 1024) where * D is the decimal equivalent of the binary code that is loaded into the DAC register. D can take on any value between 0 and 1023. This configuration ensures that the DAC is monotonic. (1) VA R R R To Output Amplifier R R Figure 26.

All amplifiers, even rail-to-rail types, exhibit a loss of linearity as the output approaches the supply rails (0 V and VA, in this case). For this reason, linearity is specified over less than the full output range of the DAC. However, if the reference is less than VA, there is only a loss in linearity in the lowest codes. The output capabilities of the amplifier are described in Electrical Characteristics. The output amplifiers are capable of driving a load of 2 k in parallel with 1500 pF to ground or to VA. The zerocode and full-scale outputs for given load currents are available in Electrical Characteristics. 8.3.2 Reference Voltage The DAC104S085 uses a single external reference that is shared by all four channels. The reference pin, VREFIN, is not buffered and has an input impedance of 30 k. TI recommends driving the VREFIN by a voltage source with low output impedance. The reference voltage range is 1 V to VA, providing the widest possible output dynamic range. 8.3.3 Power-On Reset The power-on reset circuit controls the output voltages of the four DACs during power up. Upon application of power, the DAC registers are filled with zeros and the output voltages are 0 V.

In power-down mode, the supply current drops to 20 A at 3 V and 30 A at 5 V. The DAC104S085 is set in power-down mode by setting OP1 and OP0 to 11. Because this mode powers down all four DACs, the address bits, A1 and A0, are used to select different output terminations for the DAC outputs. Setting A1 and A0 to 00 or 11 causes the outputs to be tristated (a high impedance state). While setting A1 and A0 to 01 or 10 causes the outputs to be terminated by 2.5 k or 100 k to ground respectively (see Table 1). Table 1. Power-Down Modes A1 A0 OP1 OP0 OPERATING MODE 0 0 1 1 High-Z outputs 0 1 1 1 2.5 k to GND 1 0 1 1 100 k to GND 1 1 1 1 High-Z outputs The bias generator, output amplifiers, resistor strings, and other linear circuitry are all shut down in any of the power-down modes. However, the contents of the DAC registers are unaffected when in power down. Each DAC register maintains its value prior to the DAC104S085 being powered down unless it is changed during the write sequence that instructed it to recover from power down. Minimum power consumption is achieved in the powerdown mode with SYNC and DIN idled low and SCLK disabled. The time to exit power down (Wake-Up Time) is typically tWU s as stated in Timing Requirements. 8.4.2 Bipolar Operation The DAC104S085 is designed for single-supply operation and thus has a unipolar output. However, a bipolar output may be obtained with the circuit in Figure 27. This circuit provides an output voltage range of 5 V. A railto-rail amplifier should be used if the amplifier supplies are limited to 5 V. 10 pF R2 +5V R1 +5V 10 PF + - 0.1 PF 5V + DAC104S085 -5V SYNC VOUT DIN SCLK Copyright (c) 2016, Texas Instruments Incorporated Figure 27.

See the Figure 1 for information on a write sequence. A write sequence begins by bringing the SYNC line low. Once SYNC is low, the data on the DIN line is clocked into the 16-bit serial input register on the falling edges of SCLK. To avoid misclocking data into the shift register, it is critical that SYNC not be brought low simultaneously with a falling edge of SCLK (see Figure 1). On the 16th falling clock edge, the last data bit is clocked in and the programmed function (a change in the DAC channel address, mode of operation and/or register contents) is executed. At this point the SYNC line may be kept low or brought high. Any data and clock pulses after the 16th falling clock edge is ignored. In either case, SYNC must be brought high for the minimum specified time before the next write sequence is initiated with a falling edge of SYNC. Because the SYNC and DIN buffers draw more current when they are high, they must be idled low between write sequences to minimize power consumption. 8.5.2 Input Shift Register The input shift register, Figure 28, has sixteen bits. The first two bits are address bits. They determine whether the register data is for DAC A, DAC B, DAC C, or DAC D. The address bits are followed by two bits that determine the mode of operation (writing to a DAC register without updating the outputs of all four DACs, writing to a DAC register and updating the outputs of all four DACs, writing to the register of all four DACs and updating their outputs, or powering down all four outputs). The final twelve bits of the shift register are the data bits. The data format is straight binary (MSB first, LSB last), with all 0s corresponding to an output of 0 V and all 1s corresponding to a full-scale output of VREFIN - 1 LSB. The contents of the serial input register are transferred to the DAC register on the sixteenth falling edge of SCLK. See Figure 1. LSB MSB A1 A0 OP1 OP0 D11 D10 D9 D8 D7 D6 D5 D4 D3 D2 D1 D0 DATA BITS 0 0 1 1 0 1 0 1 DAC A DAC B DAC C DAC D 0 0 1 1 0 1 0 1 Write to specified register but do not update outputs. Write to specified register and update outputs. Write to all registers and update outputs. Power-down outputs. Figure 28. Input Register Contents Normally, the SYNC line is kept low for at least 16 falling edges of SCLK and the DAC is updated on the 16th SCLK falling edge. However, if SYNC is brought high before the 16th falling edge, the data transfer to the shift register is aborted and the write sequence is invalid. Under this condition, the DAC register is not updated and there is no change in the mode of operation or in the DAC output voltages. 8.5.3 DSP and Microprocessor Interfacing Interfacing the DAC104S085 to microprocessors and DSPs is quite simple. The following guidelines are offered to hasten the design process. 16 Submit Documentation Feedback Copyright (c) 2006-2016, Texas Instruments Incorporated Product Folder Links: DAC104S085 DAC104S085-Q1 DAC104S085, DAC104S085-Q1 www.ti.com SNAS362G - MAY 2006 - REVISED APRIL 2016 Programming (continued) 8.5.3.1 ADSP-2101 and ADSP2103 Interfacing Figure 29 shows a serial interface between the DAC104S085 and the ADSP-2101 or ADSP2103. The DSP must be set to operate in the SPORT Transmit Alternate Framing Mode. It is programmed through the SPORT control register and must be configured for Internal Clock Operation, Active Low Framing and 16-bit Word Length. Transmission is started by writing a word to the Tx register after the SPORT mode has been enabled. ADSP-2101/ ADSP2103 TFS DT SCLK DAC104S085 SYNC DIN SCLK Figure 29.

The SYNC signal comes from a bit-programmable pin on the microcontroller. The example shown in Figure 30 uses port line P3.3. This line is taken low when data is transmitted to the DAC104S085. Because the 80C51 and 80L51 transmits 8-bit bytes, only eight falling clock edges occur in the transmit cycle. To load data into the DAC, the P3.3 line must be left low after the first eight bits are transmitted. A second write cycle is initiated to transmit the second byte of data, after which port line P3.3 is brought high. The 80C51 and 80L51 transmit routine must recognize that the 80C51 and 80L51 transmits data with the LSB first while the DAC104S085 requires data with the MSB first. 80C51/80L51 DAC104S085 P3.3 SYNC TXD SCLK RXD DIN Figure 30. 80C51 and 80L51 Interface 8.5.3.3 68HC11 Interface Figure 31 shows a serial interface between the DAC104S085 and the 68HC11 microcontroller. The SYNC line of the DAC104S085 is driven from a port line (PC7 in Figure 31), similar to the 80C51/80L51. The 68HC11 must be configured with its CPOL bit as a zero and its CPHA bit as a one. This configuration causes data on the MOSI output to be valid on the falling edge of SCLK. PC7 is taken low to transmit data to the DAC. The 68HC11 transmits data in 8-bit bytes with eight falling clock edges. Data is transmitted with the MSB first. PC7 must remain low after the first eight bits are transferred. A second write cycle is initiated to transmit the second byte of data to the DAC, after which PC7 must be raised to end the write sequence. 68HC11 DAC104S085 PC7 SYNC SCK SCLK MOSI DIN Figure 31. 68HC11 Interface 8.5.3.4 Microwire Interface Figure 32 shows an interface between a Microwire compatible device and the DAC104S085.

TI's customers are responsible for determining suitability of components for their purposes. Customers should validate and test their design implementation to confirm system functionality. 9.1 Application Information While the simplicity of the DAC104S085 implies ease of use, it is important to recognize that the path from the reference input (VREFIN) to the VOUTs has essentially zero Power Supply Rejection Ratio (PSRR). Therefore, it is necessary to provide a noise-free supply voltage to VREFIN. To use the full dynamic range of the DAC104S085, the supply pin (VA) and VREFIN can be connected together and share the same supply voltage. Because the DAC104S085 consumes very little power, a reference source may be used as the reference input and/or the supply voltage. The advantages of using a reference source over a voltage regulator are accuracy and stability. Some low noise regulators can also be used. Listed below are a few reference and power-supply options for the DAC104S085. 9.1.1 LM4130 The LM4130, with its 0.05% accuracy over temperature, is a good choice as a reference source for the DAC104S085. The 4.096-V version is useful if a 0 to 4.095-V output range is desirable or acceptable. Bypassing the LM4130 VIN pin with a 0.1-F capacitor and the VOUT pin with a 2.2-F capacitor improves stability and reduces output noise. The LM4130 comes in a space-saving, 5-pin SOT-23.

LM4130 as a Power Supply 9.1.2 LP3985 The LP3985 is a low-noise, ultra-low dropout voltage regulator with a 3% accuracy over temperature. It is a good choice for applications that do not require a precision reference for the DAC104S085. It comes in 3-V, 3.3-V, and 5-V versions, among others, and sports a low 30-V noise specification at low frequencies. Because lowfrequency noise is relatively difficult to filter, this specification could be important for some applications. The LP3985 device comes in a space-saving, 5-pin SOT-23 and 5-bump DSBGA packages.

Using the LP3985 Regulator An input capacitance of 1-F without any ESR requirement is required at the LP3985 input, while a 1-F ceramic capacitor with an ESR requirement of 5 m to 500 m is required at the output. Careful interpretation and understanding of the capacitor specification is required to ensure correct device operation. 9.1.3 LP2980 The LP2980 is an ultra-low dropout regulator with a 0.5% or 1% accuracy over temperature, depending upon grade. It is available in 3-V, 3.3-V, and 5-V versions, among others. Input Voltage VIN VOUT LP2980 ON /OFF 1 PF 0.1 PF VA VREFIN DAC104S085 VOUT = 0V to 5V SYNC DIN SCLK Copyright (c) 2016, Texas Instruments Incorporated Figure 35. Using the LP2980 Regulator Like any low dropout regulator, the LP2980 requires an output capacitor for loop stability. This output capacitor must be at least 1 F over temperature, but values of 2.2 F or more provides even better performance. The ESR of this capacitor should be within the range specified in the LP2980 data sheet (SNOS733). Surface-mount solid tantalum capacitors offer a good combination of small size and ESR. Ceramic capacitors are attractive due to their small size, but, generally have ESR values that are too low for use with the LP2980. Aluminum electrolytic capacitors are typically not a good choice due to their large size and have ESR values that may be too high at low temperatures. 20 Submit Documentation Feedback Copyright (c) 2006-2016, Texas Instruments Incorporated Product Folder Links: DAC104S085 DAC104S085-Q1 DAC104S085, DAC104S085-Q1 www.ti.com SNAS362G - MAY 2006 - REVISED APRIL 2016 9.2 Typical Application Input Voltage R VZ IDAC IZ 0.1 PF 0.47 PF LM4050-4.1 or LM4050-5.0 VA VREFIN DAC104S085 VOUT = 0V to 5V SYNC DIN SCLK Copyright (c) 2016, Texas Instruments Incorporated Figure 36. The LM4050 as a Power Supply 9.2.1 Design Requirements While the simplicity of the DAC104S085 implies ease of use, it is important to recognize that the path from the reference input (VREFIN) to the VOUTs has essentially zero Power Supply Rejection Ratio (PSRR). Therefore, it is necessary to provide a noise-free supply voltage to VREFIN. To use the full dynamic range of the DAC104S085, the supply pin (VA) and VREFIN can be connected together and share the same supply voltage. Figure 36 uses an LM4050 as a voltage reference source for the DAC104S085. 9.2.2 Detailed Design Procedure Available with accuracy of 0.44%, the LM4050 shunt reference is also a good choice as a reference for the DAC104S085. It is available in 4.096-V and 5-V versions and comes in a space-saving, 3-pin SOT-23. The minimum resistor value in the circuit of Figure 36 must be chosen so that the maximum current through the LM4050 does not exceed its 15-mA rating. The conditions for maximum current include the input voltage at its maximum, the LM4050 voltage at its minimum, and the DAC104S085 drawing zero current. The maximum resistor value must allow the LM4050 to draw more than its minimum current for regulation plus the maximum DAC104S085 current in full operation. The conditions for minimum current include the input voltage at its minimum, the LM4050 voltage at its maximum, the resistor value at its maximum due to tolerance, and the DAC104S085 draws its maximum current. Equation 4 and Equation 5 summerize these conditions.

The areas are defined by the locations of the analog and digital power planes. Both of these planes should be located in the same board layer. There must be a single ground plane. A single ground plane is preferred if digital return current does not flow through the analog ground area. Frequently a single ground plane design uses a fencing technique to prevent the mixing of analog and digital ground current. Separate ground planes must only be used when the fencing technique is inadequate. The separate ground planes must be connected in one place, preferably near the DAC104S085. Special care is required to ensure that digital signals with fast edge rates do not pass over split ground planes. They must always have a continuous return path below their traces. Avoid crossover of analog and digital signals and keep the clock and data lines on the component side of the board. The clock and data lines must have controlled impedances. 11.2 Layout Example 2 GND 2 GND 3 1 NetC1_1 GND G N D 1 NetC1_1 1 NetC1_1 10 2 3 2 1 NetC1_1 9 11 GND 4 5 8 1 NetC1_1 1 NetC1_1 GND 1 NetC1_1 2 GND 1 1_ 1 tC Ne 1 NetC1_1 Figure 39.

DAC-to-DAC CROSSTALK is the glitch impulse transferred to a DAC output in response to a full-scale change in the output of another DAC. DIGITAL CROSSTALK is the glitch impulse transferred to a DAC output at mid-scale in response to a full-scale change in the input register of another DAC. DIGITAL FEEDTHROUGH is a measure of the energy injected into the analog output of the DAC from the digital inputs when the DAC outputs are not updated. It is measured with a full-scale code change on the data bus. FULL-SCALE ERROR is the difference between the actual output voltage with a full scale code (3FFh) loaded into the DAC and the value of VA x 1023 / 1024. GAIN ERROR is the deviation from the ideal slope of the transfer function. It can be calculated from Zero and Full-Scale Errors as GE = FSE - ZE, where GE is Gain error, FSE is Full-Scale Error and ZE is Zero Error. GLITCH IMPULSE is the energy injected into the analog output when the input code to the DAC register changes. It is specified as the area of the glitch in nanovolt-seconds. INTEGRAL NON-LINEARITY (INL) is a measure of the deviation of each individual code from a straight line through the input to output transfer function. The deviation of any given code from this straight line is measured from the center of that code value. The end point method is used. INL for this product is specified over a limited range. LEAST SIGNIFICANT BIT (LSB) is the bit that has the smallest value or weight of all bits in a word. This value is LSB = VREF / 2n where * where VREF is the supply voltage for this product, and "n" is the DAC resolution in bits, which is 10 for the DAC104S085. (6) MAXIMUM LOAD CAPACITANCE is the maximum capacitance that can be driven by the DAC with output stability maintained. MONOTONICITY is the condition of being monotonic, where the DAC has an output that never decreases when the input code increases. MOST SIGNIFICANT BIT (MSB) is the bit that has the largest value or weight of all bits in a word. Its value is 1/2 of VA. MULTIPLYING BANDWIDTH is the frequency at which the output amplitude falls 3dB below the input sine wave on VREFIN with a full-scale code loaded into the DAC. POWER EFFICIENCY is the ratio of the output current to the total supply current. The output current comes from the power supply. The difference between the supply and output currents is the power consumed by the device without a load. SETTLING TIME is the time for the output to settle to within 1/2 LSB of the final value after the input code is updated. TOTAL HARMONIC DISTORTION (THD) is the measure of the harmonics present at the output of the DACs with an ideal sine wave applied to VREFIN. THD is measured in dB. WAKE-UP TIME is the time for the output to exit power-down mode. This is the time from the falling edge of the 16th SCLK pulse to when the output voltage deviates from the power-down voltage of 0V. 24 Submit Documentation Feedback Copyright (c) 2006-2016, Texas Instruments Incorporated Product Folder Links: DAC104S085 DAC104S085-Q1 DAC104S085, DAC104S085-Q1 www.ti.com SNAS362G - MAY 2006 - REVISED APRIL 2016 Device Support (continued) ZERO CODE ERROR is the output error, or voltage, present at the DAC output after a code of 000h has been entered. 12.2 Related Links The table below lists quick access links.
