Beschreibung

The PAM8403 is a 3W, class-D 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 thePAM8403 is much better than that of Class-AB cousins. It can extendthe battery life, which makes it well-suited for portable applications.

The PAM8403 is available in SOP-16 package.
