The PAM8403 is great little class-D stereo amplifier (3 W). Compared to the classic LM386 it is much more efficient to use in a battery powered portable project, since it is class-D.
You can find very cheap, ready-to-use boards on Ebay or AliExpress, with or without a volume pot. Or design your own board with the temporary KiCad design below, and integrate it into your own projects...
There are also other variants of this amplifier IC:
- PAM8302A (mono, 2.5 W, QFN package available)
- PAM8404 (stereo, 3W, QFN package available)
- PAM8620 (stereo, more power (15 W))
