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.

Claim (Index 1):
A liquid discharge apparatus comprising:\n a discharge unit which includes a piezoelectric element and discharges a liquid by applying a driving signal to the piezoelectric element; and a driving circuit which outputs the driving signal, wherein the driving circuit includes an output node for outputting the driving signal, a first transistor pair which includes a first transistor and a second transistor which are connected to each other in series between a first power source voltage supply line for supplying a first power source voltage and a second power source voltage supply line for supplying a second power source voltage that is higher than the first power source voltage, a comparator for comparing a voltage of an original driving signal which is an origin of the driving signal with a voltage of a first feedback signal which is a signal fed back from the driving signal, a first gate driver to which the first power source voltage and the second power source voltage are supplied and which generates a first control signal that controls a switching operation of the first transistor pair in accordance with a signal output from the comparator, and a linear amplifier which amplifies a voltage of the original driving signal by predetermined times and outputs the voltage based on a second feedback signal which is a signal fed back from the output signal thereof, wherein an output end of the first transistor pair is connected to the output node, wherein, in a first period, a switching operation of the first transistor pair is stopped and the voltage output from the linear amplifier is applied to the output node, wherein at least a part of the comparator, at least a part of the first gate driver, and at least a part of the linear amplifier are integrated in an integrated circuit device, wherein the integrated circuit device includes a first output terminal from which the first control signal is output, a first input terminal to which the first feedback signal is input, and a second input terminal to which the second feedback signal is input, and wherein 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.
