® ADS-937 ® 16-Bit, 1MHz Sampling A/D Converters GENERAL DESCRIPTION INPUT/OUTPUT CONNECTIONS The low-cost ADS-937 is a 16-bit, 1MHz sampling A/D converter. This device accurately samples full-scale input signals up to Nyquist frequencies with no missing codes. This feature, combined with excellent signal-to-noise ratio (SNR) and total harmonic distortion (THD), makes the ADS937 the ideal choice for both time-domain (CCD/medical imaging, scanners, process control) and frequency-domain (radar, telecommunications, spectrum analysis) applications. FEATURES Packaged in a 32-pin, side-brazed, metal-sealed, ceramic TDIP, the functionally complete ADS-937 contains a fastsettling sample-hold amplifier, a subranging (two-pass) A/D converter, an internal reference, timing/control logic, and error correction circuitry. Digital input and output levels are TTL. The ADS-937 only requires the rising edge of the start convert pulse to operate. 16-bit resolution 1MHz sampling rate No missing codes over full HI-REL temperature range Very low power, 1.25 Watts Small, 32-pin, side-brazed ceramic TDIP Requiring ±15V and ±5V supplies, the ADS-937 typically dissipates 1.25 Watts. The device is offered with both bipolar (±5V) and unipolar (0 to –10V) analog input ranges. Models are available in commercial (0 to +70°C), industrial (–40 to +100°C), or HI-REL (–55 to +125°C) operating temperature ranges. A proprietary, auto-calibrating, errorcorrecting circuit enables the device to achieve specified performance over the full military temperature range.

All supplies and the clock (START CONVERT) must be present during warm-up periods. The device must be continuously converting during this time. ➃ Effective bits is equal to: (SNR + Distortion) – 1.76 + 20 log Full Scale Amplitude Actual Input Amplitude 6.02 ➁ Contact DATEL for other input voltage ranges. ➂ A 1MHz clock with a 500nsec positive pulse width (50% duty cycle) is used for all production testing. Any duty cycle may be used as long as a minimum positive pulse width of 20nsec is maintained. For applications requiring lower sampling rates, clock frequencies less than 1MHz may be used. TECHNICAL NOTES ➄ This is the time required before the A/D output data is valid once the analog input is back within the specified range. THERMAL REQUIREMENTS 1. Obtaining fully specified performance from the ADS-937 requires careful attention to pc-card layout and power supply decoupling. The device's ground pins are not connected to each other internally. For optimal performance, tie all ground pins (2, 12 and 13) directly to a large analog ground plane beneath the package. The device's +5V supply pins are not connected to each other internally and should be connected to a clean analog +5V supply. Bypass all power supplies and the +5V REFERENCE OUTPUT (pin 5) to ground with 4.7μF tantalum capacitors in parallel with 0.1μF ceramic capacitors. Locate the bypass capacitors as close to the unit as possible. Tie a 47μF capacitor between COMPENSATION (pin 7) and ground (See figure 2.). 2. The ADS-937 achieves its specified accuracies without the need for external calibration. If required, the device's small initial offset and gain errors can be reduced to zero using the adjustment circuitry shown in Figure 2. When using this circuitry, or any similar offset and gain calibration hardware, make adjustments following warm-up. To avoid interaction, always adjust offset before gain. Float pins 4 and 6 if not using offset and gain adjust circuits. All DATEL sampling A/D converters are fully characterized and specified over operating temperature (case) ranges of 0 to +70°C and –55 to +125°C. All room-temperature (TA = +25°C) 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. 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. Electrically-insulating, thermally-conductive "pads" may be installed underneath the package. 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. 3. Applying a start convert pulse while a conversion is in progress (EOC = logic "1") will initiate a new and inaccurate conversion cycle. Data for the interrupted and subsequent conversions will be invalid.

Any offset/gain calibration procedures should not be implemented until the device is fully warmed up. To avoid interaction, adjust offset before gain. The ranges of adjustment for the circuits in Figure 2 are guaranteed to compensate for the ADS-937'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 is accomplished by connecting LED's to the digital outputs and performing adjustments 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-937, offset adjusting is normally accomplished when the analog input is 0 minus ½LSB (–76.3μV). See Table 2 for the proper bipolar and unipolar output coding. 3. For a bipolar input - Adjust the offset potentiometer until the output code flickers equally between 1000 0000 0000 0000 and 0111 1111 1111 1111. For a unipolar input - Adjust the offset potentiometer until all output bits are 0's and the LSB flickers between 0 and 1. GAIN ADJUST PROCEDURE 1. Apply –4.999771V to the ANALOG INPUT (pin 1) for bipolar gain adjust or apply –9.999771V to pin 1 for unipolar gain adjust. 2. For a unipolar input - Adjust the gain potentiometer until all output bits are 1's and the LSB flickers between 1 and 0. For a bipolar input - Adjust the gain potentiometer until all output bits are 1's and the LSB flickers between 1 and 0. Gain adjusting is accomplished when the analog input is at nominal full scale minus 1½LSB's (–9.999771V for unipolar and –4.999771V for bipolar). 3. To confirm proper operation of the device, vary the applied input voltage to obtain the output coding listed in Table 2. ZERO/OFFSET ADJUST PROCEDURE Table 1. Setting Output Coding Selection (Pin 35) 1. Apply a train of pulses to the START CONVERT input (pin 16) so that the converter is continuously converting. INPUT VOLTAGE RANGE 2.
