PAM8403 - Stereo Audio Amplifier Module

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 PAM8403

  • 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.
