1. A liquid discharging apparatus comprising:
an integrated circuit device; a transistor which generates an amplification modulation signal amplified from a modulation signal pulse-modulated from a source signal based on an 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 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 integrated circuit device includes a modulation portion which generates the modulation signal; a gate driver which generates the amplification control signal based on the modulation signal; and a charge pump circuit which supplies power to the gate driver, and is included in a package which has a first side and a second side that are adjacent to each other in a plan view, wherein the package includes a first package terminal, a second package terminal, a third package terminal, and a fourth package terminal, which are electrically connected to the charge pump circuit, wherein the first package terminal and the second package terminal are provided along the first side, wherein at least one of the third package terminal and the fourth package terminal is provided along the second side, wherein the first package terminal is electrically connected to a first terminal of a first capacitor, wherein the second package terminal is electrically connected to a second terminal of the first capacitor, wherein the third package terminal is electrically connected to a third terminal of a second capacitor, and wherein the fourth package terminal is electrically connected to a fourth terminal of the second capacitor. |
