Abstract
A dynamic frequency compensated operational amplifier having multiple gain settings includes a first differential to single ended amplifier stage; a second amplifier stage responsive to the first stage; a plurality of compensating capacitors; a multi-gain setting circuit for selectively setting the gain of the operational amplifier; and a control circuit, responsive to the gain set by the multi-gain setting circuit for connecting at least one of the compensating capacitors between the output and the input of the second amplifier stage for adjusting the frequency response of the operational amplifier.
