Lm386 Stereo Audio Amplifier Circuit

Now that you ve seen the bare minimum of what it takes to make an audio amplifier with the lm386 lets build a higher fidelity version with an adjustable gain control.

Lm386 stereo audio amplifier circuit. The integrated chip lm386 is a low power audio frequency amplifier requiring a low level power supply most often batteries. Does it use the 12v battery. Here is the end result of the stereo amplifier. Give power out of 500mw at 8 ohms speaker.

A great sounding lm386 audio amplifier. For the ease of reading the provided schematic only one of the two channels is shown. Utilizing 3 ics in an extension model. So they can be saved.

The parts required are. Here is the lm386 sound system sound intensifier circuit 2 watts. It can give an output power is 500mw to 700mw. Most of the component values in this circuit aren t critical.

Tda2030 stereo amplifier circuit. Pcb making is a fun project you can definitely make circuits boards so easily. And produces rich sound. Because of the long wide voltage supply range from 4v to 12v at 50ma only.

No need too much experience. Since i wanted a stereo amp and the lm386 is mono i build two identical circuits on the same board only sharing the first two decoupling capacitors c1 and 2. 500 mw power amplifier using lm386n. Using 3 ics in a bridge model.

Before moving into the circuit details let s have a peek at some of the technical specs of the ic. The lm386 amp works extremely great. The ic lm386 is a power amplifier used for amplifying small audio signals with low supply voltages. In normal we use lm386 as a small amplifier.

But this circuit is special. Pc board i used strip board lm386 ic x2. It is cheap and easy to builds for a beginner. The amp is only 1w capable of but the audio quality of the amp will not depress you.

It comes in an 8 pin mini dip package. Ic1 lm386 low voltage audio amplifier sp1 8ω 0 25w speaker b1 battery 9v. Make a great sounding lm386 audio amplifier with bass boost in this tutorial i ll first show you how to make a basic audio amplifier with an lm386 ic to demonstrate the minimum parts needed to. Lm386 is a low voltage audio amplifier and frequently used in battery powered music devices like radios guitars toys etc the gain range is 20 to 200 gain is internally set to 20 without using external component but can be increased to 200 by using resistor and capacitor between pin 1 and 8 or just with a capacitor voltage gain simply means that voltage out is 200 times the voltage in.

The designer set the circuit is the bridge mode in a stereo system. Here is lm386 stereo audio amplifier circuit 2 watts. It is modest and simple to wo. One such simple audio circuit is proposed here using the ic lm386 which requires very few other external passive components for functioning.
