Phase reversal protection

Some op amps can show a phase reversal when the common-mode voltage exceeds the

VCC range.

Phase reversal is a specific behavior of an op amp where its output reacts as if the inputs

were inverted when at least one input is out of the specified common-mode voltage.

The TSZ182 has been carefully designed to prevent any output phase reversal. The

TSZ182 is a rail-to-rail input op amp, therefore, the common-mode range can extend up to

the rails. If the input signal goes above the rail it does not cause any inversion of the output

signal as shown in Figure 60: "No phase reversal".

If, in the application, the operating common-mode voltage is exceeded please read Section

5.3: "Input pin voltage ranges".
