Gain Error Drift does not include Unipolar Offset Drift/Bipolar Zero Drift. It is effectively the drift of the part if zero-scale calibrations only were performed as is the case with
These numbers are guaranteed by design and/or characterization.
The common-mode voltage range on the input pairs applies provided the absolute input voltage specification is obeyed.
The input voltage range on the analog inputs is given here with respect to the voltage on the respective negative input of its differential or pseudo-differential pair. See Table VII

These logic output levels apply to the MCLK OUT output only when it is loaded with a single CMOS load.
Sample tested at +25 C to ensure compliance.
