Product Description


    The PAM8403 is a 3W+3W, class-D audio amplifier. It offers low THD+N, allowing it to achieve high-quality sound reproduction using a low voltage supply.

    The new filterless architecture allows the device to drive a speaker directly, requiring no low-pass output filters, thus saving 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.Well suited for portable applications.
