Abstract: A liquid discharge apparatus includes a head and a switching device. The head includes a piezoelectric element and a pressure chamber configured to discharge liquid. The switching device is configured to select application or non-application of a drive voltage waveform to the piezoelectric element. The drive voltage waveform includes a discharge waveform to pressurize and discharge the liquid in the pressure chamber and a damping waveform to suppress residual vibration in the pressure chamber. The damping waveform is disposed after the discharge waveform in time series. The switching device includes a switch and a diode. The switch is configured to be turned on in a falling waveform element of each of the discharge waveform and the damping waveform. The diode is connected in parallel with the switch in a direction opposite to the falling waveform element of each of the discharge waveform and the damping waveform.
