High-quality 3W stereo amplifier based on the PAM8403 chip. Small footprint is ideal for portable application. Low current drain. Operates on 2.5-5Vdc. 24.5 X 15.0 X 3.5mm pc board. Easy to connect, clearly marked solder or header connections. Requires the addition of a potentiometer. For a similar board with pot already onboard see CAT# AMP-8403VC.
Spec sheet available in PDF format.
It works but the pin out is very difficult to work with, I did make a PCB footprint for adding it to projects
I wish they consulted me before making these boards

This little amplifier seems to perform very well. Unfortunately the pin spacing on the board is NOT standard 0.1" so wires seem to be the only viable connection.

I used this as a common mode cable driver, as opposed to stereo outputs. The ferrites and 220pf as per the 8403 data sheet are a good idea for this application.
