Liquid ejecting apparatus and drive circuit

A liquid ejecting apparatus comprising:

• a liquid ejection head including a drive element, the liquid ejection head ejecting a liquid by a supply of a drive signal to the drive element;
• and
• a drive circuit that outputs the drive signal, wherein
• the drive circuit includes
• a modulation circuit that modulates a base drive signal to output a modulation signal,
• an amplifier circuit that amplifies the modulation signal to output an amplified modulation signal,
• a demodulation circuit that demodulates the amplified modulation signal to output the drive signal, and
• a substrate on which the modulation circuit, the amplifier circuit, and the demodulation circuit are provided,
• the substrate includes a first face and a second face opposite to the first face,
• the demodulation circuit includes a first coil and a second coil electrically coupled in parallel with the first coil,
• the first coil is positioned so as to overlap at least part of the second coil in a direction normal to the first face, and
• the first coil is provided on the first face, and the second coil is provided on the second face.
