PRODUCTION DATA
The OPA4H199-SP family 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 non-inverting circuits when the input is driven beyond the specified common-mode voltage range, causing the output to reverse into the opposite rail. The OPA4H199-SP is a rail-to-rail input op amp; therefore, the common-mode range can extend beyond 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 6-9. For more information on phase reversal, see the Op amps with complementary-pair input stages: What are the design trade-offs? Analog Design Journal.
