Abstract

A liquid ejecting apparatus includes a sink circuit that switches, in accordance with a result of determining states of a plurality of ejection sections by a state determination circuit, an impedance value between first wiring through which a reference voltage signal to be supplied to a second end of a first piezoelectric element and a second end of a second piezoelectric element propagates and second wiring through which a signal having an electrical potential lower than an electrical potential of the reference voltage signal propagates. The sink circuit has a first mode in which the impedance value is set to a first impedance value, a second mode in which the impedance value is set to a second impedance value less than the first impedance value, and a third mode in which the impedance value is set to a third impedance value less than the second impedance value.
