The PAM8403 is a 3W, class-D audio amplifier. It offers low THD+N, allowing it to achieve high quality sound reproduction. The new filter less architecture allows the device to drive the speaker directly, requiring no low-pass output filters, thus to save the 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, ideal for portable applications.
