An operational amplifier circuit (10) uses a first operational amplifier (16) to selectively provide a boosted drive current in response to an input signal voltage transitioning. The boosted driver current is used by a second operational amplifier (22) having a single high gain stage (76). The output drive current of the operational amplifier circuit (10) is increased to a predetermined maximum value for a predetermined time after an input signal transition in order to source increased current to a capacitive or inductive load only during output signal transitions. Separate current boost circuits (30, 70) in each of the first and second operational amplifiers enable early signal transition detection and ensure continuation of increased current until completion of the signal transition.
