Description
The PAM8403 is a mini digital audio amplifier module that provides two channels of stereo sound at 3 watts each. This class-D audio amplifier has low total harmonic distortion and noise, resulting in high-quality sound output. It uses a filterless architecture, which eliminates the need for low-pass output filters, saving on system cost and PCB area. Compared to its Class-AB counterparts, the PAM8403 has much better efficiency, even with the same number of external components. This makes it ideal for portable applications, as it can help extend battery life.
