Lm386 Amplifier Circuit. We need to supply an audio signal to the input of the amplifier pin 3. If you are a hobbyist then you should definitely try this simple circuit.
Note that the maximum power supply for lm386 is 15v. The schematic is a mono amplifier so if you wanted to amplify a stereo signal you d need two of these circuits one for each channel and each speaker. It is very useful in low power projects or circuits which are powered by batteries such as radio set tape player etc.
This circuit can be used as small mic and loudspeaker system for a small space like a room.
Next we need to connect the input. The main work here for the amplifier is to amplify the audio signal. You can also check the lm386 datasheet here. Next we need to connect the input.
