Customer ServiceWhen the inputs change too quickly the OpAmp''s output voltage changes at its maximum rate, called slew rate. In this case, the OpAmp''s response is nonlinear until it is able to resume linear operation without exceeding the slew rate. Such transient behavior is common in switched-capacitor circuits, where the slew rate is a major factor determining the circuit''s setting time.
