摘要:
A liquid jet apparatus according to the invention is a liquid jet apparatus adapted to emit a jet of a liquid by driving an actuator of a liquid jet head with a drive signal including a digital power amplifier and a low pass filter provided to the liquid jet head so as to correspond to the actuator, and adapted to power-amplify and smooth a modified signal from a control circuit to form the drive signal, wherein the low pass filter is coupled directly with the actuator, and the digital power amplifier is provided with a pair of switching elements and a gate drive circuit, and ON-OFF controls the gate drive circuit based on print data, thereby performing one of output and halt of the drive signal.
