Abstract
There is provided a liquid discharge apparatus including: a discharge unit which discharges a liquid by applying a driving signal to a piezoelectric element; and a driving circuit which outputs the driving signal based on an original driving signal, in which the driving circuit includes a transistor pair for outputting the driving signal, a first gate driver which generates a first control signal, and a linear amplifier which amplifies a voltage of the original driving signal, in which a first output terminal from which the first control signal is output, a first input terminal to which a first feedback signal, and a second input terminal to which a second feedback signal, and in which the shortest distance between the first output terminal and the first input terminal is longer than the shortest distance between the first output terminal and the second input terminal.
