摘要： A dynamic range compression circuit includes an attenuator that attenuates a signal at a predetermined node in an amplifier to reduce a gain of the amplifier and a gain controller that reduces the gain of the amplifier by the attenuator so that an amplitude of an output signal of the amplifier becomes an arbitrary output limit voltage in a case where an input signal having the same amplitude as that of an input-stage maximum voltage of the amplifier is input into the amplifier, and increases the gain of the amplifier by reducing a degree of attenuation of the attenuator according to a decrease of the amplitude of the input signal of the amplifier from the input-stage maximum voltage in a case where the amplitude of the input signal of the amplifier is smaller than the input-stage maximum voltage.
