PAM8403 5V 2-Channel Stereo Audio Amplifier Module
This Audio Amplifier Module utilizes the PAM8403, a 3W class-D amplifier known for its low total harmonic distortion plus noise (THD+N), ensuring high-quality sound reproduction. Its innovative filterless design allows direct connection to speakers without the need for low-pass output filters, reducing system costs and saving PCB space.
Compared to Class-AB amplifiers with similar external components, the PAM8403 offers significantly better efficiency. This efficiency extends battery life, making it ideal 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
- 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.
