The PAM8403 is a 3W, class-D audio amplifier. It offers low THD+N, allowing it to achieve high-quality sound reproduction. The novel 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 number of external components, the efficiency of the PAM8403 is much better than that of its Class-AB counterparts. It can extend battery life, which makes it well-suited for portable applications. The PAM8403 is available in a SOP-16 package.
