Compared to Class A, Class B, and Class AB amplifiers, the Class D audio amplifier can reach an efficiency of up to 90-95%. Where the maximum efficiency of a Class AB amplifier is 60-65%, because they work on the active region and exhibits low power loss, if you multiply collector-emitter voltage with the current, you can find that out.

12.221. Views 1 Comments. Cezar Chirila @ allaboutcircuits.com shows how to build a Class-D amplifier which has amazing efficiency. What is a Class-D audio power amplifier? The answer could be just a sentence long: It is a switching amplifier. But in order to fully understand how one works, I need to teach you all its nooks and crannies.
TinyD, 8-bit stereo class D amp from Attiny85 | Hackaday.io
https://hackaday.io/project/19178-tinyd-8-bit-stereo-class-d-amp-from-attiny85
Description. The goal of this project is to create an 8-bit 32khz stereo class d amplifier controlled by an Attiny85. I built a similar model back in 2014 based off the ATtiny461. This new version will be ported to the more popular ATtiny85. I changed the scope of this project due to time constraints.
