Abstract:
Provided is a liquid discharging apparatus which includes a modulation circuit which generates a modulation signal which is obtained by pulse-modulating a source signal, a transistor which generates an amplified modulation signal by amplifying the modulation signal, a low pass filter which generates a drive signal by smoothening the amplified modulation signal, a piezoelectric element which is displaced by receiving the drive signal, and a circuit substrate on which the transistor is mounted. The transistor includes a first electrode, a second electrode, a third electrode, and a clip which has conductivity, is electrically connected to the first electrode. Furthermore, the circuit substrate has a first land corresponding to the first electrode, a second land corresponding to the second electrode, and a third land corresponding to the third electrode. In addition, a part of the clip is connected to the third land.
