Adinol you have just confused me in understanding the fact. Louis on November 28, at 1: You can use another value lm386b all of the capacitors, but they should around the same value.

Risks are eventual continuous current coming from the source blows the LM IC, or worst case a problem ratasheet this amplifier circuit, causing continuous current flowing to the source, makeing hot-dogs of your connected smart phone. Do i need to learn C programme.

I just want to ask if this is an active or passive loudspeaker? And can i use this same circuit to power a watta speaker? Kev on April 22, at 1: Where is vatasheet schmetic diagram? I am at your mercy sir if any amount to be paid i am ready to pay.


You could use a small boost converter. Earvin Ladera on March 29, at 7: Hi Onur, according to the datasheet, the LMN-1 has the lowest minimum voltage requirement, which is 4 volts… So a 3.

LM386 (M-82) Audio Amplifier

Notify me of new posts by email. If your gain is set tothe range of volume is 0 to The pin 7 is used to connect datasheef filtering capacitor 0. The pin 1 and pin 8 are used to set the gain of the Amplifier.

Great little article, thanks. A cool feature of the LM is the option to add an adjustable bass boost to the amplifier. Sir i am also interest to do this circuit, And I need speaker specification In which Rate of Speaker to be work on this circuit with best bass and volume Reply.

Anthony on September 16, at 8: What are the specifications of output speaker?

Build a Great Sounding Audio Amplifier (with Bass Boost) from the LM386

Hi, Is this amplifier have enough power to fill a 4m x 4m room? I need to break-in my new subs.

Randy on September 19, at 6: Roger on July 6, at Thank you for the article and all the circuits. A Good Job of explaining this. S Prakash Rao on July 11, at 1: I have tried this circuit and it worked.


To use it as a mic pre amp, you would connect your mic to the input of the amp, then instead of having a speaker connected to the output, you would connect the output to your recording device. I am your fan. And what do I have to do to make it work with l,386n Sanjeev Chauhan on February 24, at Here C2 and R1 are in series. Would you please help? If your voltage is lower than the minimum, the power output will be very low and the audio will probably distort.

You explained all this just at the right level so a newbie, as I am, could follow your process and understand it…well most of it a few more re-reads should nail the rest. Venkatagireesh on October 27, at Hi Sanjeev, double check to make sure everything is connected properly, and the dattasheet of the electrolytic capacitors are correct….

One of those caps is a 0.
