A Class D audio amplifier is basically a switching amplifier or PWM amplifier. There are a number of different classes of amplifiers. We will take a look at the definitions for the main ...

The active components of the Class D amplifier are the switching output stage and modulator. This circuitry can be built for roughly the same cost as an analog linear amplifier. The real trade-offs ...

If you know anything about a transistor, it’s probably that it’s a three terminal device whose output pin forms part of a potential divider whose state is dependent on what is presented to its input ...

Editor Bill Wong takes a look at Diodes' 12-W PAM8965 audio-amplifier evaluation module. The PAM8965 Class-D stereo audio power amplifier drive two channels with 12 W to a pair of 4 Ω speakers. The ...
