Class-D Amplifier Circuits Design Considerations for Class-D Audio Power Amplifiers 3 The internal gain of the class-D amplifier limits the input voltage to a maximum of VIN PO RL AV where PO is the maximum output power, R L is the dc load resistance, and A V is the internal gain of the class-D amplifier. The large gain and low input currents

Most audio system design engineers are well aware of the power-efficiency advantages of Class D amplifiers over linear audio-amplifier classes such as Class A, B, and AB. In linear amplifiers such as Class AB, significant amounts of power are lost due to biasing elements and the linear operation of the output transistors.

Here is the output voltage seen in a typical Class-D amplifier with a slightly underdamped output filter. You can see the PWM 3usec signal (330KHz) superimposed on the lower frequency square-wave, and you can see the overshoot (at about 25KHz) which has resulted from the underdamped filter, resonant in the mid-20s KHz.
