A liquid ejecting device includes: an ejection section that includes a piezoelectric element that is displaced upon application of a drive signal, and ejects a liquid upon displacement of the piezoelectric element; 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; and 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, 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. |
