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.
