The 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.
Application :
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
