Audio Amplifier Circuit Diagram Using Lm386. Circuit b will give a gain around 50. The audio signal also needs its own path to gnd.
Circuit a will give a voltage amplification of 200. Diy lm386 audio amplifier. The circuit is using lm386 amplifier ic maximum gain of the circuit can be set between 20 to 200 the 10uf capacitor from pin 1.
Below is a schematic diagram of a lm386 circuit lm386 amp which can be used as a simple audio amplifer to increase the audio of your radio mp3 players etc.
Diy lm386 audio amplifier. Circuit b will give a gain around 50. Hi there today we will be learning how to make an audio amplifier using smd version of lm386. The circuit c is not for voltage amplification but will raise the bass level by about 5 db.
