8.3.2 Phase-Reversal Protection

The OPA1688 has internal phase-reversal protection. Many op amps exhibit 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 OPA1688 prevents phase reversal with excessive common-mode voltage. Instead, the appropriate rail limits the output voltage. Figure 8-2 shows this performance.
