Following the digital clipper, the interpolated audio data is next sent to the closed-Loop Class-D amplifier, whose first stage is Digital to PWM Conversion (DPC) block. In this block, the stereo audio data is translated into two pairs of complimentary pulse-width- modulated (PWM) signals which are used to drive the outputs of the speaker amplifier. Feedback loops around the DPC ensure constant gain across supply voltages, reducing distortion and improving immunity to the power supply noise. The analog gain is also applied in the Class-D amplifier section of the device.
