1 These specifications were determined without the use of the gain calibration feature.

2 See the Terminology section.

3 Samples tested during initial release to ensure compliance; they are not subject to production testing.

4 For PGA gain = 1; to use the full analog input range (VCM ± VREF/2) of the AD7262, the VCM voltage should be dropped to lie within a range from 1.95 V to 2.05 V.

5 Refers to Pin VREFA or Pin VREFB.

6 This specification includes the IDD for both comparators. The IDD per comparator is the specified value divided by two.
