2 channel amplifier board

PAM8403 5V Two-Channel Stereo Audio Amplifier Module is based on PAM8403 which 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. 

Features :

• Dual-channel stereo, high output power (3 w + 3 w power @ 5V and 4 ohms load).

• Supermini design allows it to be easily placed in a variety of digital products.

• Good sound quality.

• Thermal Shutdown

• Double panel wiring solves crosstalk.

• Filterless, Low Quiescent Current, and Low EMI.

• Superior Low Noise.

• Short Circuit Protection.

• 3W Output at 10% THD with a 4ΩLoad and 5V Power Supply.

Application :

• Speaker Phones.

• Bluetooth Stereo Audio hands-free/headsets.

• LCD Monitors / TV Projectors.

• In robots that speak or generate sounds to indicate activities

• Portable Speakers.

• Arduino or Raspberry Pi Game Machines.
