Class D Audio Amplifier Tutorial
Afrotechmods shows us how a Class D Audio Amplifier works and how to build one. A TPA3122 is a class D amplifier on a chip. There are no external power components needed since class D amplifiers use mosfets for switching and thus the heat dissipation is low enough that it can be squished into the DIP package with no heatsinking needed. “The TPA3122D2 is a 15-W (per channel) efficient,
