Lm386 Amplifier Circuit Diagram. One such simple audio circuit is proposed here using the ic lm386 which requires very few other external passive components for functioning. Circuit diagram of the the bass booster amplifier.
We will look at the datasheet info the circuit diagram in eagleeda then the pcb in eagle eda and finally the actual hardware. Circuit diagram of the the bass booster 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 to 8 is used to set the gain of 200.
Quote hi the circuit is to amplify a mic signal before sending to a headphone ic.
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 to 8 is used to set the gain of 200. The main work here for the amplifier is to amplify the audio signal. You should be using an opamp for the preamp stage. Hi there today we will be learning how to make an audio amplifier using smd version of lm386.
