... Full Scale Amplitude Actual Input Amplitude 3. Pin 35 (COMP . BITS) is used to select the digital output coding format of the ADS-935. See Tables 2a and 2b. When this pin has a TTL logic "0" applied, it complements all of the ADS-935’s digital outputs. When pin 35 has a logic "1" applied, the output coding is complementary (offset) binary. Applying a logic " ...

... FIFO Reset Feature At any time, the FIFO can be reset to an empty state by putting the ADS-935 into its "direct" mode (logic "0" applied to pin 8, FIFO/DIR) and also applying a logic "0" to the FIFO READ line (pin 9). The empty status of the FIFO will be indicated by FSTAT1 going to a " ...

... To avoid interaction, adjust offset before gain. The ranges of adjustment for the circuits in Figure 2 are guaranteed to compensate for the ADS-935’s initial accuracy errors and may not be able to compensate for additional system errors. ...
