7.3.2 Phase-Reversal Protection

The OPAx170-Q1 family has an internal phase-reversal protection. Many operational amplifiers exhibit a phase reversal when the input is driven beyond the linear common-mode range. This condition is most often encountered in noninverting circuits when the input is driven beyond the specified common-mode voltage range, causing the output to reverse into the opposite rail. The input of the OPAx170-Q1 prevents phase reversal with excessive common-mode voltage. Instead, the output limits into the appropriate rail. Figure 37 shows this performance.
