ABSTRACT:
In a driver, a voltage-follower-type operational amplifier receives current input data to generate an output signal. A transient state detecting circuit detects a transient state in the current input data to generate a first pulse signal when the current input data is increased and generate a second pulse signal when the current input data is decreased. A switch circuit substantially increases corresponding load currents flowing through the voltage-follower-type operational amplifier in accordance with the first and second pulse signals.
