Slew Rate

Our Take

With op-amps (or any other amplifier/driver) there is a speed limit on how quickly the output voltage can change. This speed limit, measured in volts per second (or more commonly, volts per microsecond), is called the slew rate.

Book Definition

The rate of change of the output voltage of an op-amp in response to a step input.
