Product Description

    Details

    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.

    • Dual channel stereo, high output power (3 w + 3 w power @ 5V and 4 ohms load)
    • Good sound quality
    • Can use computer USB for power supply directly. Double panel wiring solves crosstalk
    • Super mini design allows it to be easily placed in a variety of digital products.
    • 3W Output at 10% THD with a 4ΩLoad and 5V Power Supply
