Stereo audio amplifier 2x3W D-class based on PAM8403

Stereo audio amplifier 2x3W D-class based on PAM8403

Output power 2х3W, at supply voltage 5V, load 4Ω

PAM8403 2x3W stereo D-class amplifier. Low coefficient of non-linear

distortion allows you to get high quality sound with sufficient

output power. New, filterless PAM8403 architecture with

directly connecting the speakers, thereby greatly simplifying

harness and circuit as a whole (and cost). The effectiveness of modern

D-class amplifiers are much higher than analog (AB-class) amplifiers with almost

the same sound quality, the main application is portable electronics

self-powered (acoustic systems in laptops, tablets,

monitors, portable TVs...).
