6.3.4 Phase Reversal Protection

The TLV914x family has internal phase-reversal protection. Many op amps 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 TLV914x is a rail-to-rail input op amp; therefore, the common-mode range can

extend up to the rails. Input signals beyond the rails do not cause phase reversal; instead, the output limits into

the appropriate rail. This performance is shown in Figure 6-5. For more information on phase reversal, see Op

amps with complementary-pair input stages: What are the trade-offs? Analog Design Journal.
