1 These specifications were determined without the use of the gain calibration feature.
2 See the Terminology section.
3 Samples are tested during initial release to ensure compliance; they are not subject to production testing.
4 For PGA gain = 1, to utilize the full analog input range (V
CM ± VREF/2) of the AD7264, the VCM voltage should be dropped to lie within a range from 1.95 V to 2.05 V.
5 Refers to Pin V
REFA or Pin VREFB.
6 This specification includes the I
DD for both comparators. The IDD per comparator is the specified value divided by 2.
