Abstract

A liquid ejecting apparatus includes a drive circuit. The drive circuit includes an integrated circuit, an amplifier circuit, a demodulation circuit, and a feedback circuit. The integrated circuit includes a modulation circuit, a constant voltage output circuit, and an input terminal to which the feedback signal is input. The modulation circuit and the constant voltage output circuit are coupled to the input terminal, a first virtual line segment located between the input terminal and the constant voltage output circuit in a first virtual straight line connecting the input terminal and the constant voltage output circuit at a shortest distance does not intersect the modulation circuit, and a second virtual line segment located between the input terminal and the modulation circuit in a second virtual straight line connecting the input terminal and the modulation circuit at a shortest distance does not intersect the constant voltage output circuit.
