Hi-Efficient 20W Mono Class-D Audio Amplifier
https://www.electronics-lab.com/project/hi-efficient-20w-mono-class-d-audio-amplifier/
This is a Hi-Efficient 20W mono Class-D audio amplifier, designed to drive speakers as low as 4 ohms in a bridge-tied-load configuration. Due to the low power dissipation and high efficiency of up to 90%, the module doesn’t require a heatsink. The project is built using PAM8320 chip which features short circuit protection, thermal shutdown, […]
