Digital Power Amplifier Module (PAM8403, 2*3W, 2.5V-5V)

The PAM8403 is a 3W 3W, class-D audio amplifier. It offers low THD N, allowing it to achieve high-quality sound reproduction. The 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, including Arduino. Applicationss include: 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
