The most common audio power amplifier operates in the Class-AB mode. It provides the greatest amount of output power with the least amount of distortion. The downside is that it consumes quite a bit ...

A class-D puts out a pulse-width modulated (PWM) signal instead of the typical class-AB amplifiers linear signal The PWM signal contains the audio signal and the PWM switching frequency plus harmonics ...

We know Class D audio amplification offers advantages in efficiency and size for battery-powered devices. What you may not know, however, is that these advantages can now extend to amplifiers up to ...
