This tutorial discusses two related topics related to op amps: output phase reversal, and input over-voltage protection. Output voltage phase-reversal is a problem that occurs in some op amps when the input common-mode (CM) voltage is exceeded. It is usually caused when one of the internal stages of the op amp no longer has sufficient bias voltage across it and subsequently turns off.
