LM386 Audio Amplifier Circuit
In this article we are going to show you a simple LM386 audio amplifier circuit. Circuit diagram of the LM386 audio amplifier circuit is shown in the given below diagram and animated picture. It is built by using popular amplifier LM386 (IC). We have used 8-ohm speaker, one-watt speaker, four electrolyte capacitors. We have used 6 volts power supply as power. This circuit can be used in many applications like portable intercoms,MP3 players, radio amplifiers, TV sound, Ultrasonic devices etc.

In this circuit we have used 10k pot to adjust the voice volum and it also control the voice quality.
Animated Circuit with full components detail
IC LM386 is a famous low power audio amplifier, it consumes low power supply like batteries in electronics and electrical circuits. This IC consists of 8 pins. Voltage gain of this amplifier can be adjusted to 20, and gain voltage will be 200 by connecting external components like capacitors as well as resistors among the pins’ no 8 and 1. As the amplifier uses 6 volts power supply for operation than the static power drains 24 mill watts to make the amplifier. This IC consists of 8-pins where pin-1 and pin-8 are gain control of the amplifier.
