1 Temperature range is as follows: B Version: −40°C to +85°C.

2 See the Terminology section.

3 VCM is the common-mode voltage. For full common-mode range, see Figure 25 and Figure 26. VIN+ and VIN− must always remain within GND/VDD.

4 Sample tested during initial release to ensure compliance.

5 This device is operational with an external reference in the range of 0.1 V to VDD. See the Reference section for more information.

6 Measured with a midscale dc analog input.
