(R) ADS-118, ADS-118A (R) 12-Bit, 5MHz, Low-Power Sampling A/D Converters PRODUCT OVERVIEW DATEL's ADS-118 and ADS-118A are 12-bit, 5MHz, sampling A/D converters packaged in space-saving 24-pin DDIP's. The ADS-118 offers an input range of 1V and has three-state outputs. The ADS-118A has an input range of 1.25V and features direct adjustment of offset error. These functionally complete low-power devices (1.8 Watts) contain an internal fast-settling sample/ hold amplifier, a 12-bit subranging A/D converter, a precise voltage reference, timing/control logic, and error-correction circuitry. All timing and control logic operates from the rising edge of a single start convert pulse. Digital input and output levels are TTL. Models are available for use in either commercial (0 to +70C) or military (-55 to +125C) operating temperature ranges. Applications include radar, transient signal analysis, process control, medical/graphic imaging, and FFT spectrum analysis.

All supplies and the clock (start convert pulses) must be present during warmup periods. The device must be continuously converting during this time. Input voltage ranges for ADS-118A is 1.25V A 100ns wide start convert pulse is used for all production testing. For applications requiring less than an 5MHz sampling rate, wider start convert pulses can be used. NOTE: The device only requires the rising edge of a start convert pulse to operate. Full Scale Amplitude Actual Input Amplitude (SNR + Distortion) - 1.76 + 20 log 6.02 This is the time required before the A/D output data is valid once the analog input is back within the specified range. The minimum supply voltages of +4.9V and -4.9V for VDD are required for -55C operation only. The minimum limits are +4.75V and -4.75V when operating at +125C TECHNICAL NOTES 1. Obtaining fully specified performance from the ADS-118 requires careful attention to pc-card layout and power supply decoupling. The device's analog and digital ground systems are connected to each other internally. For optimal performance, tie all ground pins (14, 18, and 23) directly to a large analog ground plane beneath the package. Bypass all power supplies to ground with 4.7F tantalum capacitors in parallel with 0.1F ceramic capacitors. Locate the bypass capacitors as close to the unit as possible. 2. The ADS-118 achieves its specified accuracies without the need for external calibration. If required, the device's small initial offset and gain DATEL * errors can be reduced to zero using the adjustment circuitry shown in Figures 2a and 2b. For operation without adjustment, tie pin 17 to analog ground. When using this circuitry, or any similar offset and gain-calibration hardware, make adjustments following warmup. To avoid interaction, always adjust offset before gain. 3. To enable the three-state outputs, connect ENABLE (pin 17) to a logic "0" (low). To disable, connect pin 17 to logic "1" (high). The three-state outputs are permanently enabled in the ADS-118A. 4. Applying a start convert pulse while a conversion is in progress (EOC = logic "1") will initiate a new and inaccurate conversion cycle. 11 Cabot Boulevard, Mansfield, MA 02048-1151 USA * Tel: (508) 339-3000 * www.datel.com 31 Mar 2011 * e-mail: help@datel.com ADS-118.B03 Page 3 of 8 (R) ADS-118, ADS-118A (R) 12-Bit, 5MHz, Low-Power Sampling A/D Converters CALIBRATION PROCEDURE Any offset and/or gain calibration procedures should not be implemented until devices are fully warmed up. To avoid interaction, offset must be adjusted before gain. The ranges of adjustment for the circuits in Figures 2a and 2b are guaranteed to compensate for the ADS-118's initial accuracy errors and may not be able to compensate for additional system errors. A/D converters are calibrated by positioning their digital outputs exactly on the transition point between two adjacent digital output codes. This can be accomplished by connecting LED's to the digital outputs and adjusting until certain LED's "flicker" equally between on and off. Other approaches employ digital comparators or microcontrollers to detect when the outputs change from one code to the next. For the ADS-118, offset adjusting is normally accomplished at the point where the MSB is a 1 and all other output bits are 0's and the LSB just changes from a 0 to a 1. This digital output transition ideally occurs when the applied analog input is +1/2LSB (+244V for ADS-118; +305V for ADS-118A). Zero/Offset Adjust Procedure 1. Apply a train of pulses to the START CONVERT input (pin 16) so the converter is continuously converting. 2. Apply +244V (ADS-118) or +305V (ADS-118A) to the ANALOG INPUT (pin 19). 3. Adjust the offset potentiometer until the output bits are 1000 0000 00000 and the LSB flickers between 0 and 1. Gain Adjust Procedure 1. Apply +0.99927V (ADS-118) or +1.249085V (ADS-118A) to the ANALOG INPUT (pin 19). 2. Adjust the gain potentiometer until all output bits are 1's and the LSB flickers between 1 and 0. 3. To confirm proper operation of the device, vary the input signal to obtain the output coding listed in Table 1. Gain adjusting is accomplished when all bits are 1's and the LSB just changes from a 1 to a 0. This transition ideally occurs when the analog input is at +full scale minus 11/2 LSB's (+0.99927V for ADS-118; +1.249085V for ADS-118A). Table 1.

Devices should be soldered to boards rather than socketed, and of course, minimal air flow over the surface can greatly help reduce the package temperature. All DATEL sampling A/D converters are fully characterized and specified over operating temperature (case) ranges of 0 to +70C and -55 to +125C. All room temperature (TA = +25C) production testing is performed without the use of heat sinks or forced air cooling. Thermal impedance figures for each device are listed in their respective specification tables. In more severe ambient conditions, the package/junction temperature of a given device can be reduced dramatically (typically 35%) by using one of DATEL's HS Series heat sinks. See Ordering Information for the assigned part number. See page 1-183 of the DATEL Data Acquisition Components Catalog for more information on the HS Series. Request DATEL Application Note AN8, "Heat Sinks for DIP Data Converters", or contact DATEL directly, for additional information. These devices do not normally require heat sinks, however, standard precautionary design and layout procedures should be used to ensure devices do not overheat. The ground and power planes beneath the package, as well as all pcb signal runs to and from the device, should be as heavy as possible to help conduct heat away from the package. +0.67 0 DNL (LSB's) -20 -30 -40 Number of Occurences Amplitude Relative to Full Scale (dB) -10 -50 -60 -70 -80 -90 -100 0 -0.47 0 4096 Digital Output Code -110 -120 -130 0 250 kHz 500 kHz 750 kHz 1 MHz 1.25 MHz 1.5 MHz 1.75 MHz 2 MHz Frequency (fs = 5MHz, fin = 2.45MHz, Vin = -0.5dB, 4,096-point FFT) 2.25 MHz 2.5 MHz 0 4096 Digital Output Code Figure 6.
