Abstract
A liquid ejecting apparatus includes a differential signal output circuit that outputs a pair of differential signals based on an original control signal, a pair of first signal wirings that are electrically coupled to the differential signal output circuit and propagate the differential signals, a first receiving circuit that is electrically coupled to the first signal wirings, a second receiving circuit that is electrically coupled to the first signal wirings, and an ejector that includes a drive element and that ejects a liquid from a nozzle by driving the drive element, in which the first receiving circuit outputs a control signal for controlling driving of the drive element based on the differential signals, power consumption of the first receiving circuit is larger than power consumption of the second receiving circuit, and the first receiving circuit and the second receiving circuit are electrically coupled by a second signal wiring.
