Liquid ejecting device, driver circuit, and head unit

A driver circuit that drives a capacitive load with a drive signal, the driver circuit comprising:

• a comparator unit that includes a first comparator section and a second comparator section, receives an input signal and the drive signal, and outputs a first control signal and a second control signal;
• a transistor pair that includes a first transistor that is controlled based on the first control signal and a second transistor that is controlled based on the second control signal, and outputs the drive signal;
• a first offset section that lowers the input signal by a first voltage, or raises the drive signal by the first voltage;
• and
• a second offset section that raises the input signal by a second voltage, or lowers the drive signal by the second voltage,
• the first transistor and the second transistor being located electrically in series between the power supply voltages,
• the drive signal being output from a terminal that is a connection point of the first transistor and the second transistor,
• the first comparator section comparing a first comparison signal and a second comparison signal and outputting the first control signal,
• the first comparison signal being a signal obtained by offsetting one of the input signal and the drive signal,
• the second comparator section comparing a third comparison signal and a fourth comparison signal and outputting the second control signal, and
• the third comparison signal being a signal obtained by offsetting one of the input signal and the drive signal.
