Sample tested during initial release to ensure compliance.

4

For dc accuracy specifications, the LSB size for differential mode is FSR/8192. For single-ended mode/pseudo differential mode, the LSB size is FSR/4096, unless

otherwise noted. FSR is the theoretical difference between the max and min input values.

5

Unipolar 0 V to 10 V range with straight binary output coding.

6

Bipolar range with twos complement output coding.
