Lm386 Stereo Audio Amplifier Circuit. Here is lm386 stereo audio amplifier circuit 2 watts. In normal we use lm386 as a small amplifier.
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. The ic lm386 is a power amplifier used for amplifying small audio signals with low supply voltages. That amplification is what s known as the voltage gain.
This circuit can be used as small mic and loudspeaker system for a small space like a room.
Lm386 ic x2 dip 8 ic socket x2 optional but suggested speaker x2 4 to 8 ohms each at least 1 watt female spade terminals to connect speaker wires to speaker optional but suggested stereo audio jack. But this voltage gain can be raised up to 200 vu 200 by adding external parts. The integrated chip lm386 is a low power audio frequency amplifier requiring a low level power supply most often batteries. In an amplifier circuit the lm386 takes an audio input signal and increases its potential anywhere from 20 to 200 times.
