The PAM8403 from Diodes Inc. is a 3W, Class-D Stereo Audio Amplifier. It offers low THD+N, allowing it to achieve high-quality sound reproduction. The new filterless architecture allows the device to drive the speaker directly, requiring no low-pass output filters, thus saving system cost and PCB area.

With the same numbers of external components, the efficiency of the PAM8403 is much better than that of Class-AB amplifiers. It can extend the battery life, which makes it well-suited for portable applications.
