Lm386 5v Audio Amplifier Circuit Diagram. Lm386 is basically an opamp. We need to supply an audio signal to the input of the amplifier pin 3.
A great sounding lm386 audio amplifier. The audio signal also needs its own path to gnd. The gain is internally set to 20 but it can be modified from 20 to.
If you use the external circuit a replace the rx with a jumper wire in the pcb.
The lm386 is a mono low voltage amplifier that can be used in a variety of applications. Before using this project test it using the 6v battery. Ic lm386 is a famous low power audio amplifier it consumes low power supply like batteries in electronics and electrical circuits. A great sounding lm386 audio amplifier.
