Abstract
There is provided a driving circuit that drives a discharge head which includes a piezoelectric element, the driving circuit including: a first voltage signal output circuit that outputs the first voltage signal by operating based on an amplification control signal; and an integrated circuit that outputs the amplification control signal, in which the integrated circuit includes an amplification control signal generation circuit, an output control circuit, and a first register, in which the amplification control signal generation circuit generates the amplification control signal based on a drive data that defines a signal waveform of the first voltage signal input from an input terminal, in which the first register holds an operating state data that defines the operating state of the driving circuit input from the input terminal, and in which the output control circuit controls an output of the driving circuit based on the operating state data.
