1. A driver comprising:

  • a voltage-follower-type operational amplifier for receiving current input data to generate an output signal;

    a transient state detecting circuit for detecting a transient state in said current input data to generate a first pulse signal when said current input data is increased and generate a second pulse signal when said current input data is decreased; and

    a switch circuit, connected between said transient state detecting circuit and said voltage-follower-type operational amplifier, for substantially increasing corresponding load currents flowing through said voltage-follower-type operational amplifier in accordance with said first and second pulse signals.
