PAM8403 Module Super Mini Digital Amplifier Board 2 3W Class D 2.5V to 5V USB Power Supply

PAM8403 5V Two-channel Stereo is a 3W+3W, class-D audio amplifier. 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.
