PAM8403 Stereo Audio Amplifier Module – 3W Output, Adjustable Volume, 5V-Powered Mini Amp

Description

The PAM8403 is a 3W classD 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 lowpass 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 classAB cousins. It can extend the battery life ideal for portable applications.
