PAM8403 5V Two Channel Stereo Audio Amplifier Module is based on PAM8403 which is a 3W, class-D audio mini 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. This 5v audio amplifier board 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.
