7.4.1 Common-Mode Voltage Range

The input common-mode voltage range of the OPAx171-Q1 family of devices extends 100 mV below the negative rail and within 2 V of the top rail for normal operation.

This device can operate with full rail-to-rail input 100 mV beyond the top rail, but with reduced performance within 2 V of the top rail. The typical performance in this range is listed in Table 7-1.
