- On-Board IC: PAM8403
- Module Pin count: 9
- IC type: Stereo Audio Amplifier
- Manufacturer: Generic
- The package contains 1 x PAM8403 audio amp module.
Module Overview 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.

NOTE Violating these safety measures may lead to total product damage and such products are not eligible for refund or replacement.
Input audio should be via shielded wire for the best performance
Use properly filtered and regulated power supply.
Take care not to short speaker wires else IC will get damaged.
Make sure the power supply never exceeds 5.5V else IC will get damaged.
The module should be connected with the speaker before it?s powered on otherwise the module may damage easily.
