Abstract
According to an aspect of the invention, there is provided a drive circuit for driving a capacitive load. The drive circuit comprises an amplification circuit for amplifying an input signal and outputting the amplified signal to the capacitive load and an operation state detection circuit for detecting an operation state of output operation to the capacitive load in the amplification circuit. A variable resistor is connected between the amplification circuit and the capacitive load and changes the resistance value according to the detected operation state.
