 Module Overview                                                          This Audio Amplifier Module is based on PAM8403 which 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.
