Abstract
A liquid ejecting apparatus includes a drive element, and a drive circuit that outputs a drive signal that drives the drive element. The drive circuit includes an integrated circuit that outputs an amplification control signal, an amplifier circuit that output an amplified modulation signal, and a demodulation circuit that output the drive signal. The integrated circuit includes a modulation circuit that modulates the base drive signal to output a modulation signal, a discharge circuit that discharges a charge based on the drive signal, a constant voltage output circuit that outputs a DC voltage signal, and an output terminal from which the DC voltage signal is output. The constant voltage output circuit and the discharge circuit are electrically coupled to the output terminal, and a shortest distance between the output terminal and the constant voltage output circuit is shorter than a shortest distance between the output terminal and the discharge circuit.
