Phase-Reversal Protection

Many operational amplifiers exhibit a phase reversal when the input drives beyond their specified input common-mode range. This condition is most often encountered in non-inverting circuits when the input drives beyond the specified common-mode voltage range, which can cause the output to reverse into the opposite rail. The OPA828 has an internal phase-reversal protection circuitry. The input architecture of the OPA828 prevents phase reversal with input common-mode voltages that exceed the specified maximum and minimum values. The OPA828 output limits to the appropriate rail. This performance is shown in Figure 42. When input voltages can exceed the minimum or maximum specified limits, care must be taken to limit the maximum input current through internal ESD protection diodes.
