ABSTRACT:
A capacitive load driving circuit has an input terminal, a front-edge delay circuit delaying a front edge of an input signal input via the input terminal, a back-edge delay circuit delaying a back edge of the input signal, an amplifying circuit amplifying a drive control signal obtained through the front-edge delay circuit and the back-edge delay circuit, and an output switch device which is driven by the amplifying circuit. The front-edge delay circuit includes a first time-constant circuit having a first resistor and a first capacitor, the back-edge delay circuit includes a second time-constant circuit having a second resistor and a second capacitor, and the drive control signal is generated by a signal combining circuit which combines an output signal of the first-time constant circuit with an output signal of the second-time constant circuit.
