PAM8403 Mini 5V Digital Amplifier Board With Switch Potentiometer

Description The PAM8403 is a 3W+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. Applications Bluetooth Stereo Audio hands free / headsets In robots that speak or generate sounds to indicate activities Portable Speakers LCD Monitors / TV Projectors Arduino or Raspberry Pi Game Machines Speaker Phones
