This part, an 8 pin bridgable 1W audio amplifier with volume control input is going obsolete and last order date is end of this year.
When I designed it in around 10 years ago they were old then but plenty available. We will eventually need to design in a replacement.
We are running these at around 9V VCC and they work great into a small speaker. 8 Ohms I believe.
We also use the volume control input... +40 dB gain down to -60 or 80 dB gain. Doesn't require that much gain necessarily.
There is the old National/TI LM386-4 that I just now heard is going obsolete ! Dang. It looked like it was going to work.
Could go discreet with op-amp and SOT-23s but still wouldn't have the volume/gain control pin without adding a Jfet or something and would take up valuable space on one of the existing products.
Any suggestions ?
