Abstract
An audio codec circuit includes a voltage detecting circuit, an output processing circuit, a digital-to-analog conversion circuit, and an audio amplifying circuit. The voltage detecting circuit is configured to detect an input voltage of an input power. The output processing circuit obtains a first output compensation value according to the input voltage, an output circuit parameter, and a first output spec. The output processing circuit processes a digital audio and compensates the processed audio by the first output compensation value. The digital-to-analog conversion circuit is configured to perform digital-to-analog conversion on the compensated audio to obtain an analog audio. The audio amplifying circuit is configured to amplify the analog audio and output the amplified audio.
