This 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 of PAM8403 Module:-
- Dual channel stereo output 3 w + 3 w power Class D
- Works with 2.5V-5v power supply
- High amplification efficiency 85%
- can directly drive 4 O/8 O small speakers
- Good sound quality & noise suppression
- Unique without LC filter class D digital power board
- Can use computer USB power supply directly
- Small Size, 1.85 x 2.11 cm can easily fit in a variety of products
Note when using:-
- Input audio should be via shielded wire for best performance.
- Use proper filtered power supply with good filter capacitors.
- Take care not to short speaker wires else IC will get damaged.
- Make sure power supply never execeds 5.5V else IC will get damaged. Use regulated power supply.
