DRIVE CIRCUIT OF RECORDING HEAD AND IMAGE RECORDING APPARATUS

WIPO Patent Application WO/2016/181946

A1

Provided are a drive circuit of a recording head and an image recording apparatus, capable of more easily and stably suppling power to load elements of the recording head while preventing deterioration of voltage waveforms. The drive circuit 30 of the recording head supplies, with respect to a load element provided on the recording head such as an actuator 51 of the recording element, drive voltage in accordance with operation of the load element. The drive circuit 30 is provided with a voltage amplification unit 31 that amplifies the voltage of an analog input signal Vin in accordance with the operation of the load element and generates a drive voltage signal Vd, a current amplification unit 33 that amplifies, and outputs as an output signal Vout, the current of the drive voltage signal; and a feedback unit 34 that provides, as a negative feedback, the voltage amplification unit with a feedback signal in accordance with the voltage of the output signal.
