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

Arslan on April 3, at Sure, I just added schematics for each circuit… Reply. I am doing so to attempt to convert from 9v to 12v. Hariz on November 15, at And what do I have to do to make it work with speakers?

WillW on December 18, at 5: May I know what are the voltage of all the capacitor used? I suggest building figure 10 in the St micro datasheet. Chris on July 18, at 4: Matthew on December 14, at 2: I built a stereo amp a while ago and fixed me some nice pc speakers.

RickS on July 21, at Your design and description has really helped me to design one very easily and really datasheey well. Is it normal or it is feeding to much power to the speaker or something? Mine was working right away datashert really surprised at the clarity. Thanks again, great article and video, too.


I used an 8 ohm speaker, but anything from 4 to 16 ohms will work. Apparently also my other comment got lost… Any changes I would otherwise need to make for a 12V DC adapter? Best to apparently just use a 12V battery or batteries in series if you need any higher than on here.

I took a lot of time to see Reply. 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.

Hope this makes is clear, without a revised schematic. Colby on July 3, at 2: Rajesh on September 22, at 4: Has someone an circuit for this? And BTW, nice work!

Dekisugi on March 19, at 6: This is actually explained in the article. Aniket Sarkar on March 19, at Murat on March 8, at 2: I wanna bass boost circuit. Tony Clayton on December 4, at 4: Cant seem to figure out what is wrong cos i followed the diagram exactly without success. Alex Goldman on March 26, at 8: I imagine it would be the same as an opamp.


Is there any cheap and good quality stereo amplifier for headphones? When multiple by 20, it becomes 10V which is larger than the battery voltage itself.

Sorry if this question seems idiotic to you xD I am just a beginner in this field. So the input signal will get oversteered fairly quick.

Can I ask for the flow of the circuit? Bandid on October 12, at 8: Segway on January 31, at The idea is to put another capacitor as close as possible to pins 4 and 6 to maximize the lm386-n1. Alex on August 10, at Naveed Hassan on February 19, at 7: Tem como fazer stereo?
