Abstract: <P>PROBLEM TO BE SOLVED: To provide a liquid ejection device enhanced in efficiency by properly controlling a power supply voltage applied to a digital power amplifier.  <P>SOLUTION: When a modulated signal PWM generated by pulse-modulating a drive waveform signal WCOM in a modulation circuit 26 is power-amplified in a digital power amplifying circuit 28, and the power amplified modulation signal is smoothed by a smoothing filter 29 so as to generate a drive signal COM for an actuator 22, the power supply voltage VDD applied to the digital power amplifying circuit 28 supplied by a variable power supply circuit 39 is controlled while being varied at each drive pulse PCOM. In addition, the voltage fluctuation of the drive signal COM (drive pulse PCOM) while varying the power supply voltage VDD is avoided by stopping the operation of the digital power amplifying circuit 28 before varying the power supply voltage VDD and resuming the operation of the digital power amplifying circuit 28 after varying the power supply voltage VDD.  <P>COPYRIGHT: (C)2011,JPO&INPIT
