Description
TDA7267 1W-2W Small Audio Amp
Needed a little amp for a signal generator. Something that will run on a 9v battery. This worked out very well. You can use a WH148 pot for a basic volume control and have the PCB mounted off the pot.
OK so the chip is obsolete, but its cheap and still works well - so who cares. If you are running it a little hard simple mount a Raspberry Pi heatsink directly on top the the IC. 9mm x 9mm x 12mm works very well.

TDA7267 1W-2W Small Audio Amp
2 Layers PCB 42.2 x 42.8 mm FR-4, 1.6 mm, 1, HASL with lead, Green Solder Mask, White silkscreen
Need a quick little audio amp for a bit of test gear. Runs happily from 5v to 18v straight in to a 4 ohm or 8 ohm speaker.
