I have a question about that 0. Your design and description has really helped me to design one very easily and really working well. Roger on July 6, at Do i spend money for that.

I used the LM and looking to replace it for the L3m86n-1 How come the magnified signal is not clipped or badly distorted? Sunil Vishwakarma on October 10, at 9: Sir, thank you for the great tutorial it really helps a lot can you give us an schematic diagram?
I am about to try the same thing stereo.
What was the lm368n-1 of the speaker you used? I know very little about electronics, but to me it seems that the 0. Thanks man it is working perfectly fine but i want to use it on biger speakers for louder sound. I would like to add the other channel stereo by duplicating all relevant components.
The LM cannot amplify more than the input voltage, if you have a 1V input signal the output will max out at 5V. Sanjeev Chauhan on February 24, at Jesyca JC on October 24, at 8: Ryan on December 22, at 7: No you dont need to learn c language…. Could you post a link to the video? Is it normal or it is feeding to much power to the speaker or something? I was in search of such kind of detailed tutorial.
Oh btw, i was trying to make the minimal llm386n-1 aduio amplifier. I am working on a research paper for my senior design class at UCF. Mark on October 9, at Official Hoverboards on May 18, at 7: You could use a small boost converter. Mike T on September 6, at I would like to replicate this circuit. On the presented circuits an important capacitor is missing, the source input cc decoupler.
The LM is a type of operational amplifier Op-Amp. I want to know the voltages too of each capacitor: Could u please send me an updated schematic? Arturs Spiridonovs on May 12, at I used a 4 ohm speaker Reply.
DevRoy on September 5, at 4: Fran on June 24, at 7: Sir I datasheett to use a condenser microphone as my input instead of using audio jack. As an old Pensioner 72 just starting out in electronics I have completed my your first amplifier. Great circuit LM with bass boost. I suggest building figure 10 in the St micro datasheet.
Tuck on May 13, at 1: The only diagrams I have are already included in the article. Hi Sanjeev, double check to make sure everything is connected properly, and the polarity of the electrolytic capacitors are correct….
It would be nice if you could post it and make it available to everyone. Could you tell me more about the theory here? It is also misplaced in the schematic. Thanks for an exceptionally clear tutorial. Is there any advantage to supplying the LM with datasbeet instead of something closer to the minimum 4v it requires?

NiCk nick on December 8, at 4: In neither case do I hear a change in volume when adjusting the potentiometer. I imagine it would be the same as an opamp. Nuwan madusanka on October 13, at 1: Classified was meant to be class a and water energy was meant datasyeet be wasted energy.
Any suggestions on whether the audio signal can just be parallel or would I need separate audio signals?
