ELECTRICAL CHARACTERISTICS
Note 8: See the Applications Information section for a detailed
discussion of input and output common mode range. Input common
mode range is tested by measuring the differential DC gain with V
= mid-supply, and again with V
limits listed in the Electrical Characteristics table, with ΔV
verifying that the differential gain has not deviated from the mid-supply
common mode input case by more than 0.5%, and that the common
mode offset (V
mode offset by more than ±10mV.
Output common mode range is tested by measuring the differential DC
gain with V
at the output common range limits listed in the Electrical Characteristics
