Drive circuit, and control method of drive circuit

A control method for controlling a drive circuit, the control method comprising:

• controlling one of a high-side transistor and a low-side transistor of an amplifier of the drive circuit to perform a switching operation in at least a part of a first period by a control signal generator, the drive circuit including the control signal generator and the amplifier, the control signal generator being configured to generate a control signal, based on a drive signal, which drives a capacitive load, and a source drive signal which is a source signal of the drive signal, the amplifier including the high-side transistor and the low-side transistor which are configured to be controlled based on the control signal, the amplifier being configured to output the drive signal from an output terminal of the amplifier to drive the capacitive load during a first period and a second period, the first period being a period in which a voltage changes to be higher than or equal to a first voltage per unit time, the second period being a period in which the voltage changes to be lower than the first voltage per unit time or does not change;
• and
• controlling the one of the high-side transistor and the low-side transistor to perform a linear operation in at least a part of the second period by the control signal generator.
