6-channel class D amplifier

Basic operation of a class-D amplifier

Basically, the output stage of a class-D amplifier outputs a continuous square wave swinging between positive and negative power supplies

with a fixed frequency (“clock” frequency) far beyond the audible range. The duty cycle of this square wave is modulated with the audio signal.

The output is followed by a low-pass filter which eliminates the clock frequency and allows only the audio signal going to the speaker. See

simplified drawing below.

Compared to a conventional power amplifier the benefits of the Class-D amplifier are:

• higher effiency

• lower power dissipation

• smaller heatsink required

• smaller mains transformer required

The main disadvantage of this concept is:

• The amplifier is operating with a high-frequency square wave at high amplitude and currents. This requires special precautions to prevent

excessive electromagnetic radiation (EMC).
