Claim:
1. A liquid discharging apparatus comprising: a modulation portion which generates a modulation signal pulse-modulated from a source signal; a gate driver which generates an amplification control signal based on the modulation signal; a transistor which generates an amplification modulation signal amplified from the modulation signal based on the amplification control signal; a low pass filter which demodulates the amplification modulation signal and generates a driving signal; a piezoelectric element which is displaced as the driving signal is applied; a first power source portion which applies a constant voltage signal to a terminal which is different from a terminal to which the driving signal of the piezoelectric element is applied; a temperature detection portion which detects temperature; a cavity in which the inside is filled with liquid and the internal volume changes due to the displacement of the piezoelectric element; and a nozzle which communicates with the cavity, and discharges the liquid inside the cavity as liquid droplets in accordance with the change in the internal volume of the cavity, wherein the first power source portion is disposed on the shortest straight path between the temperature detection portion and the gate driver.
