Abstract
A first signal line for supplying a potential to one terminal of a capacitive load, a first switch element for supplying a first potential to the first signal line, a first drive circuit for driving the first switch element, and a second signal line for supplying a second potential different from the aforesaid first potential to the one terminal of the capacitive load are included. A first capacitor is capable of supplying a lower potential than the first and the third potentials to the first signal line. A coil circuit is connected between the first signal line or the second signal line and a supply line for supplying the third potential. A floating power supply circuit supplies power supply voltage with a potential of the first signal line as a reference to the first drive circuit.
