Abstract
A controllerthat conducts various controls corresponding to input information selects target voltage information and target dead time information corresponding to input audio signal level information from data table information, outputs the target voltage information to a variable power supply unit, and outputs the target dead time information associated with the target voltage information to a dead time generator, to thereby set an output supply voltage and a dead time corresponding to an input audio signal level in a half bridge circuit. Accordingly, there can be provided a class D amplification device that can minimize the dead time and reduce distortion while suppressing the amount of heat generation caused by a through-current.
