Abstract
An operational amplifier includes an input stage configured to receive a first input voltage and a second input voltage and a slew boost circuit coupled to the input stage and configured to selectively increase current through the input stage. The operational amplifier also includes an output stage coupled to the input stage and configured to generate an output voltage, and a slew boost disable circuit configured to assert a control signal to the slew boost circuit to disable the slew boost circuit. The slew boost circuit is disabled when both: the first input voltage being more than a first threshold voltage different from the second input voltage and the output voltage failing to change by more than a second threshold rate.
