LM386 (M-82) Audio Amplifier

I agree to let Circuit Basics store my personal information so they can email me the file I requested, and agree to the Privacy Policy Email me new tutorials and very occasional promotional stuff: NOME on December 30, at 1: I make this circuit. I have tried this circuit and it worked.

I built a stereo version of this using 2. Then there is a 0. It does sound a bit better.

But I have a question about the gain of I just dataxheet to ask if you can send me a copy of the schematics because im not used to bread boards which is I am really ashamed of, LOL. Hoping to be of some help. The pin 1 and pin 8 are used to set the gain of the Amplifier. Sipan Hadji on February 13, at 9: Adinol on December 23, at 7: I have watt speakers if they are okay with the IC LM or not?????

I also want to add an FM radio on it. The notch is on the side that goes up, so pin 1 will be on the left of the notch, and pin 8 will be on the right. Mark on October 9, at Hello, I am working on a research paper for my senior design class at UCF. Will it work with a guitar with two humbuckers? Gerard on August 25, at 9: Can I use k pot????? Jefferson Yagdulas on March 3, at 3: Please send me the schematic diagram.

The pF cap to eliminate datashest noise is excellent. I used an 8 ohm speaker, but datasheer from 4 to 16 ohms will work. I wanted to make a portable speaker out of an old speaker box I bought a couple of months ago and your circuit with bass boost was exactly what I needed.

Email me new tutorials and very occasional promotional stuff: Cant seem to figure out what is wrong cos i followed the diagram exactly without success Reply. Keeping the wires as short as possible will also help.

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

It should be between pin 3 and GND, not pin 2. Just run the positive input straight into pin 3…. What is the range of the …-1 chip ac voltage output?

For that I think you would be better of building a dedicated subwoofer amplifier, or using a tone control circuit. But you specify the voltage of each capacitor Reply.

Adinol you have just confused me in understanding the fact. Shall I get good quality sound for datasheett What am I missing? Many persons who are new to the world wide web, or perhaps are merely going through the opportunity to start an online business question when it is really vital to their success to get a blog.

I datawheet like to add the other channel stereo by duplicating all relevant components. My lm chip starte heating up once I had connected the cell — any idea why?! Really fun to be driving powerless 8ohm speakers from the Android phone or PC. Excellent tutorial I managed to make the first two today and will work on the final versions next.
