ABSTRACT:
A driving circuit capable of implementing voltage reduction and attaining high-speed operation and high precision while controlling currents consumed by two through current control transistors independently of each other is obtained. This driving circuit comprises a first differential circuit including a first through current control transistor, a second differential circuit including a second through current control transistor and an output circuit including a first conductivity type first output transistor having a gate supplied with an output of the first differential circuit and a second conductivity type second output transistor having a gate supplied with an output of the second differential circuit. A first potential is supplied to the gate of the first through current control transistor of the first differential circuit while a second potential is supplied to the gate of the second through current control transistor of the second differential circuit.
