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

Features :

  • Dual channel stereo, high output power (3 w + 3 w power @ 5V and 4 ohms load).
  • Good sound quality.
  • Double panel wiring solves crosstalk.
  • Super mini design allows it to be easily placed in a variety of digital products.
  • 3W Output at 10% THD with a 4ΩLoad and 5V Power Supply.
  • Filterless, Low Quiescent Current and Low EMI.
  • Superior Low Noise.
  • Short Circuit Protection.
  • Thermal Shutdown
  • Input audio should be via shielded wire
  • big output power, sound quality is good.
  • Unique without LC filter class D digital power board
  • can use computer USB power supply directly
  • high amplification efficiency
  • made with solid plate welding machine
