PAM8403 5V 2-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
