PAM8403 - Stereo Audio Amplifier Module

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. 

We have Various sizes of Audio, Sound and Voice Module. Check out our complete collection of Audio, Sound and Voice Module.


If you are in Nashik you can buy this Electronic Component at our local shop at New CBS, Nashik or you can place order online and get it delivered at your doorstep anywhere in India.
