Claim 0:
1. A liquid discharging apparatus comprising:
a drive signal output circuit outputting a drive signal that displaces between a first potential and a second potential that is lower than the first potential; and
a discharging portion including a piezoelectric element that is driven based on the drive signal and discharging liquid by a drive of the piezoelectric element, wherein
the drive signal output circuit includes
a modulation circuit that outputs a modulation signal obtained by modulating a base drive signal that is a base of the drive signal,
an amplification circuit that outputs an amplified modulation signal obtained by amplifying the modulation signal, and
a demodulation circuit that includes a capacitor and outputs the drive signal obtained by demodulating the amplified modulation signal,

the first potential is 25 V or higher, and
the capacitor is a surface mounting component including a laminated portion in which a resin thin film layer and a metal thin film layer are laminated.
