Lm386 Audio Power Amplifier Circuit Diagram. The loudspeaker use 4 ohms or 8 ohms. Schematic diagram and description of a lm386 circuit lm386 amp the circuit is using lm386 amplifier ic and few components.

Take note that the circuit c is to be connected between pins 1 and 5 of the ic. The loudspeaker use 4 ohms or 8 ohms. Before using this project test it using the 6v battery.

This circuit can be used for increasing the audio of small radio mp3 player etc.

Lm386 mini audio amplifier circuit. By default it offers a bandwidth of 20 but we can increase it by adding external resistors and capacitors with pin1 and pin8. This circuit can be used for increasing the audio of small radio mp3 player etc. Four electrolytic capacitors are used in this circuit.
