LM386 Audio Amplifier Circuit
This high quality LM386 audio amplifier circuit uses a LM386 IC. The LM386 comes in 3 flavors now; LM386-1, LM386-2, LM386-3 with output power levels of 300, 500 and 700 millwatts respectively. The 10K pot controls the gain and the 220uF capacitor couples the output to the speaker. A Very simple and high quality amplifier for general purpose work. The 8 Ohm speaker can be replaced with a set of 8 Ohm earphones when used as some type of listening device, i.e. spy device.
