PAM8403 Audio Amplifier Module

The PAM8403 is a popular, ultra-miniature, efficient 3W+3W Class-D stereo audio amplifier IC often found on small modules for DIY projects, offering high-quality sound from low-voltage (2.5V-5.5V) power sources like USB or batteries, ideal for portable speakers, computers, and hobby electronics due to its small size, low heat, and built-in volume control. Key features include high efficiency (up to 90%), low distortion, and protection features, but it requires careful wiring, especially connecting speakers before power, to ad damage.
