“Class” is in session. This discussion of electronic amplifier circuits offers an overview of the characteristics that define commonly used class designations ...

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 ...

A new generation of digital-input Class D audio amplifiers achieves high PSRR performance that is comparable to traditional analog Class D amplifiers. More importantly, digital-input Class D ...

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 ...
