Introduction

AI Translation

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 the PAM8403 is much better than that of Class- AB cousins. It can extend the battery life, which makes it well- suited for portable applications.

The PAM8403 is available in SOP- 16 package.
