... A/D converter, an internal reference, timing/control logic, and error-correction circuitry. Digital input and output levels are TTL. The ADS-931 only requires the rising edge of the start convert pulse to operate. Requiring only ±5V supplies, the ADS-931 dissipates 1.85 Watts. The device is offered with a bipolar (± ...

... The minimum limits are +4.75V and –4.75V when operating at +125°C. 3. Pin 35 (COMP. BITS) is used to select the digital output coding format of the ADS-931 (see Tables 2a and 2b). When this pin has a TTL logic "0" applied, it complements the ADS- 931’s B1-B16 & B1 outputs. ...

... If the output three-state register has been enabled (logic "0" applied to pin 34), data from the first conversion will appear at the output of the ADS-931. Attempting to write a 17th word to a full FIFO will result in that data, and any subsequent conversion data, being lost. ...

... To avoid interaction, adjust offset before gain. The ranges of adjustment for the circuits in Figure 2 are guaranteed to compensate for the ADS-931’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 ...
