Abstract
A class D amplifier includes an amplifier that generates a digital signal for driving a load based on an input signal, an attenuator that attenuates the input signal according to an attenuation command signal, and a clip prevention controller that outputs the attenuation command signal to intermittently attenuate the input signal when the digital signal is brought into a clip state or a near-clip state.
