A drive circuit includes a modulation circuit that modulates a base drive signal that is a base of a drive signal, and outputs a modulation signal, an amplification circuit that outputs a first amplified modulation signal obtained by amplifying the modulation signal, a level switching signal generation circuit that generates a level switching signal that is a digital signal, a level shift circuit that outputs the first amplified modulation signal as a second amplified modulation signal, or outputs, as the second amplified modulation signal, a signal obtained by shifting a potential of the first amplified modulation signal, and a demodulation circuit that demodulates the second amplified modulation signal, and outputs the drive signal. A voltage of the drive signal is lower than a power supply voltage of the level shift circuit when the level shifts circuit shift a potential of the first amplified modulation signal.
