Description
The PAM8403 5V Two-channel Stereo is a class-D audio amplifier that delivers 3W+3W of high-quality sound. It has a filter less architecture that enables it to drive the speaker directly without low-pass output filters, saving system cost and PCB area. The PAM8403 is more efficient than Class-AB counterparts with the same number of external components. This makes it ideal for portable applications as it can prolong the battery life.
