Description:
The LM386 amp is an affordable, simple to use chip. The chip is nowhere near high power or high end (for a high-end amp, see the LM3886 68W amp), as it only delivers about 250mW (about 1/4 watts). A good use for this chip is for low power computer speakers, audio buffers, etc.

Pinout:
The pinout is not shown on the schematic above, and nor is the power supply pins. Here is the pinout from the datasheet: (Copyright National Semiconductor)
Useage:
This amplifier has an advantage of operating off of a single power supply. I tested it with a standard 9V battery, and it worked great. It should even run off of a 6V lantern battery.
