TECHNICAL INFORMATION CLASS-T DIGITAL AUDIO AMPLIFIER EVALUATION BOARD USING EB-TA0102 DIGITAL POWER PROCESSING TM TECHNOLOGY January 2001, For Rev. 3.3 Board General Description The EB-TA0102 evaluation board is based on the TA0102A digital audio power amplifier from Tripath Technology. This board is designed to provide a simple and straightforward environment for the evaluation of the Tripath stereo TA0102A amplifier. This board can also be used in a bridged configuration for high power mono output.

Vspos and Vsneg power the load and so must each be able to provide half of the desired output power, plus about 20% for overhead and margin. The TA0102A amplifier also requires a supply, VN12, that is 12V more positive than Vsneg and tracks Vneg. This evaluation board generates this VN12 voltage on-board. All input, output and power supply connections are made using tinned wire or female banana connectors (not shown). Though not required, the following powering-up sequence is usually adhered to during bench st nd rd evaluations: 1 ) +5V, 2 ) Vsneg and 3 ) Vspos (refer to the Turn-on/off Pop section). The positive and negative supply voltages do not have to match or track each other, but distortion or clipping levels will be determined by the lowest (absolute) supply voltage. For applications where VN12 is supplied separately, make sure this supply tracks the Vsneg as it becomes more negative with respect to ground. Once power is applied to the evaluation board, the green power light, LED 1, will illuminate. If it does not, power the unit down and recheck all connections and supplies. If the MUTE jumper is missing, the LED will not illuminate. To un-mute, short pins 2 and 3 of JP5. Please note that until the Vspos and Vsneg have powered up and are within the undervoltage and overvoltage limits, the LED will be illuminated (assuming everything else is properly connected). Once the amplifier is switching, if the undervoltage or overvoltage limit is violated, LED 1 will turn off until supply voltages are within specification. Input Connections Audio input to the board is located at IN1 and IN2 (see Figures 1 and 2). The input can be a test signal or music source. Connections are made using tinned wired to IN1, IN2 and Analog Ground, AGND. These connections are made on the evaluation board using a cable harness with female banana connectors (not shown). Output Connections There are four female banana connectors on the evaluation board for speaker outputs OUT1, OUT2, and Power Grounds, GND1 and GND2 (see Figures 1 and 2; cable harness connections are not shown). The TA0102A can be operated as a two channel single-ended amplifier, bridged mono output amplifier (see Figure 8) or with a passive crossover for a 2.1 channel application (refer to Application Note 13). Outputs can be any passive speaker(s) or test measurement equipment (see Application Note 4 "Parametric Measurements" for more information on bench testing). Note: To avoid performance degradation, the Analog Ground and Power Grounds should be kept separate. They are internally connected in the TA0102A amplifier.

Turn-on/off Pop To avoid turn-on pops, bring the mute from a high to a low state after all power supplies have settled. To avoid turn-off pops, bring the mute from a low to a high state before turning off the supplies. The only issue with bringing up the 5V last or turning it off first is clicks/pops. If the mute line is properly toggled (slow turn-on, quick turn-off), then any power up sequence is fine. In practice, the 5V will usually collapse before Vspos and Vsneg. This is acceptable and will not cause any damage to the TA0102A.

In Output Section TA0102A Input Stage The major functional Out VN12 Figure 3 Input Stage Figure 4 shows one channel of the Input Stage. The TA0102A amplifier is designed to accept unbalanced inputs and provide an overall gain of 7.05, or approximately 17 dB. Please note that the input stage of the TA0102A is biased at approximately 2.5VDC. Therefore, for an input signal centered around ground (0VDC), the polarity of the coupling capacitor, CIN , shown in Figure 4 is correct. 49.9K RIN 1uF, 6.3V + Input to TA0102A (DC Bias ~2.5V) CIN +5V 1M 1M 10K 0.1uF, 50V Figure 4 EB-TA0102 01.01, Rev. 3.3 5 TECHNICAL INFORMATION The gain of each channel of the TA0102A amplifier is set by the value of resistor RIN in Figure 4 (labeled R8 and R9 on the schematic), according to the following equation: 3 Av = 387 x 10 / (RIN + 5000) where RIN is in Ohms In this design, RIN is 49.9K, which yields an Av of 7.05 (17 dB). This value is a good compromise between gain and noise, though reducing RIN by a factor of two will only increase the noise generated inside the TA0102A by ~1 dB. The values of the input capacitor, CIN in Figure 4 (labeled C13 and C16 on the schematic), and the input resistor, RIN , set the -3dB point of the input high-pass filter. The frequency of the input high pass pole, FP, of the -3dB point can then be calculated as follows: FP = 1/(2 x CIN )(RIN + 5000) where: CIN = input capacitor value in Farads RIN = input resistor value in Ohms Output offset voltages can be nulled by adjusting the 10K potentiometer shown in Figure 4. Once set, the offset does not typically drift with temperature, so no tracking circuitry is required. Offsets can typically be set to +/- 25 mV. R43 is used to adjust the offset of CH1, and R42 is used to adjust the offset of CH2. If a different TA0102A is placed in the EB-TA0102 evaluation board, the offset of each channel would need to be re-trimmed. TA0102A Control Circuitry The 5V supply drives the power light, LED 1, directly to indicate a "good" status. If the LED 1 is off, the amplifier is in HMUTE (see Figure 5). HMUTE goes high (i.e. LED1 is off), when a fault condition occurs. If this is caused by an overcurrent condition, the mute pin must be cycled (i.e. low to high to low) to clear the fault. If the fault was caused by an over- or undervoltage, simply bring the supply rails to within the OV and UV specifications for the TA0102A (+28V to +49V). Once the supply is within these limits, the amplifier will automatically reset and LED 1 will illuminate. As stated previously, until the supplies Vspos and Vsneg are within the specified range, LED 1 will be illuminated. It would be impossible for the TA0102A to report a supply voltage fault during power up without requiring a specified supply voltage power sequence that is clearly undesirable. +5V AGND MUTE +5V Pin 4 The MUTE pin is brought out to an external 3-pin header, JP5 (Figure 5). When a jumper is installed from Pin 4 to ground (by shorting pins 2 and 3 on JP5), the MUTE line is pulled to ground and the outputs are enabled. Note that if the MUTE jumper is removed, the MUTE pin floats high, the amplifier is muted and the power LED will not be lit. This is done to remind the user of a possible "jumper off" condition if there is no output. If the MUTE jumper is driven from the external MUTE connection to Pin 4 and left floating, the outputs are muted. JP5 LED 1 MUTE OCR2 10 4 R10 BBM0 R OCR 8 OCR1 35 JP3 +5V 11 BBM1 6 IN2 AGND IN1 R11 MUTE HMUTE 7 Figure 5 EB-TA0102 01.01, Rev. 3.3 JP4 TECHNICAL INFORMATION The resistors, ROCR in Figure 5 (labeled R10 and R11 in the schematic), set the overcurrent threshold for the output devices. Note that these are NOT the sense resistors (the overcurrent sense resistors, RS, are in the output stage). By adjusting the ROCR resistor values, the threshold at which the amplifier "trips" can be changed. The range that the overcurrent trip point can be adjusted (by changing ROCR) is determined by the value of the sense resistors. ROCR on this evaluation board is pre-set to 10K for a 4 application. For lower impedance applications (i.e. 4 bridged), this board's overcurrent may trip prematurely. This is indicated by HMUTE going high; to clear, toggle the mute or cycle the power. To reduce overcurrent sensitivity, decrease the value of ROCR until the sensitivity meets the desired level. ROCR can be reduced to 0 though this may result in an overcurrent threshold that is so high the amplifier will try to drive a short circuit, possibly damaging the output FETs. Finally, the Break-Before-Make (or "BBM") lines are used to control the "dead time" of the output FETs. The "dead time" is the period of time between the turn-off of one device and the turn-on of the opposite device on the same channel. If the two devices are both on at the same time, current "shoots through" from one supply to the other, bypassing the load altogether. Obviously, this will have a great impact on the overall efficiency of the amplifier. However, if the dead time is too long, linearity suffers. The optimum BBM setting will change with different output FETs, different operating voltages, different layouts and different performance requirements. For this reason, Tripath has provided a means to adjust the BBM setting among four preset levels by moving jumpers JP3 and JP4 on their 3-pin headers (see Figure 5). These settings should be verified over the full temperature and load range of the application to ensure that any thermal rise of the output FETs and TA0102A does not impact the performance of the amplifier. This amplifier board is set to 65nS, and the table below shows the BBM values for various settings of the jumpers (Figure 6). 1) 2) 3) 4) BBM1 BBM0 Delay 0 0 1 1 0 1 0 1 145nS 105nS 65nS 25nS + BBM1 (board labeled BBM0) JUMPER "1" + BBM0 (board labeled BBM1) JUMPER "1" Figure 6 EB-TA0102 01.01, Rev. 3.3 7 TECHNICAL INFORMATION Output Section The output section includes the gate resistors, FETs, output filters, the previously mentioned OVERCURRENT sense resistors, clamping diodes, a Zobel, and various bypass capacitors.

They also dissipate a portion of the power resulting from moving the gate charge each time the MOSFET is switched. If RG is too small, excessive heat can be generated in the driver. Large gate resistors lead to slower gate transitions resulting in longer rise/fall times and thus requiring a larger BBM setting. Tripath recommends using an RG of 10 when the gate charge (Qg) of the output FET is less than 70nC and 5.6 when the Qg is greater than 70nC. The output FETs, M1-M4, provide the switching function required of a Class-T design. They are driven directly by the TA0102A through the gate resistors. The devices used on the evaluation board are ST STP19NB20 MOSFETs. The TA0102A data sheet contains information on output FET selection as well as Tripath application notes "FETs - Selection and Efficiency" and "Designing with Switching Amplifiers for Performance and Reliability". The output filters L1/C4 and L2/C21 are the low-pass filters that recover the analog audio signal. One of the benefits of the Class-T design is the ability to use output filters with relatively high cutoff frequencies. This greatly reduces the speaker interactions that can occur with the use of lower-frequency filters common in Class-D designs. Also, the higher-frequency operation means that the filter can be of a lower order (simpler and less costly). The OEM may benefit from some experimentation in the filter design, but the values provided in the reference design, 11.3uH and 0.22uF, provide excellent results for most loads between 4 and 8. 8 EB-TA0102 01.01, Rev. 3.3 TECHNICAL INFORMATION As important as the values themselves, the material used in the core is important to the performance of the filter. Core materials that saturate too easily will not provide acceptable distortion or efficiency figures. Tripath recommends a low-mu (10) type 2 iron powder core. The clamping diodes D1-D4 are required to limit the reverse voltages seen by the output FETs as a result of normal operation. The diodes should be mounted with short leads, as close as possible to the FET. Only Schottky diodes should be used here due to their very low forward voltage drop and fast switching. The diodes should have a forward current rating of at least one Ampere. The Zobel circuits R3/C5 and R14/C22 are there in case an amplifier is powered up with no load attached. The Q of the LC output filter, with no load attached, rises quickly out to 80kHz. Resonant currents in the filter and ringing on the output could reduce the reliability of the amplifier. The Zobel eliminates these problems by reducing the Q of the network significantly above 50kHz. Modifying the LC output filter should not require a recalculation of the Zobel values. The bypass capacitors C12/C27 are critical to the reduction of ringing on the outputs of the FETs. These parts are placed as closely as possible to the leads of the FETs, and the leads of the capacitors themselves are as short as practical. Their values will not change with different output FETs. EB-TA0102 01.01, Rev. 3.3 9 TECHNICAL INFORMATION Connection Diagram for Bridge Mode Operation The amplifier is connected to the power supplies and load as shown in Figure 8. Note that an inverter has been added in front of one of the channel inputs (i.e. channel 2). The main reason for processing the channels out of phase is to avoid potential problems with switching power supplies, but it also simplifies the connections for bridged-mode operation. For bridged operation, simply connect the "-" terminal to the output of the inverted channel (i.e. channel 1) and the "+" terminal to the output of the non-inverted channel with respect to the input signal (i.e. channel 2). As stated before, the TA0102A is an inverting amplifier. *Please note the Break-Before-Make labels on the PC Board are incorrect and are reversed. .

Figure 8 10 EB-TA0102 01.01, Rev. 3.3 TECHNICAL INFORMATION VN12 Bias Requirement The VN12 circuit (Figure 9) is used to provide the voltage rail for the low side FET drivers on the TA0102A. This supply must track the Vsneg rail, and so, for simplicity, this supply is included on this amplifier board (the corresponding +12V "floating" supply is generated internal to the TA0102A amplifier and so is not shown). The VN12 circuit uses a National LM2594HVN-12 "simple switcher" voltage regulator for all control. A few passive components complete the design. Tripath does not anticipate that there will be any reason to modify the operation of this circuit. Should the OEM wish to do so, however, reference data for the LM2594 is available at www.national.com/pf/LM/LM2594.
