Saturation - Non-Linear

  • An ideal op amp could provide an infinite output voltage range.
  • A very good op amp could provide outputs at least up to the power supply voltages.
  • Most op amps fall short by about two volts so with a 12 volt supply, the output would be only ten volts.
  • The output should be directly proportional to the input. That is perfectly linear.

The image below shows ideal (black line) and non-ideal (red and blue lines) behaviour including clipping when the op amp is saturated and the output voltage can go no higher.
