The LM is a type of operational amplifier Op-Amp. Simon Tay on August 28, at 8: I usually just double the voltage for the circuit….

NOME on December 30, at 1: It would be nice if you could post it and lm36n-1 it available to everyone. I also want to add an FM radio on it.

Roger on July 6, at I am having a problem with the extended bass circuit. If your voltage is lower than the minimum, the power output will be very low and the audio will probably distort.

What is the voltages of the electrolytic capacitors? For example, you can connect the grounds for the power supply, input, and output directly to the ground pin pin 4 of the LM like this:.

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

datashert I want to rebuild the 1st circuit with the pin 1 connected on the pin 8. The circuit operates at 9V, so any capacitor voltage rating above about 16V will work dstasheet. Dear sir Resenltly i purchased the Arduino Duo board for INR but when i conected to my laptop asked me to download soft ware and i down loaded. If I was to replace the 3. Gert datashset September 25, at 8: 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: Get a Linux distro, you can do pretty much everything from the command line.


Joedho on September 1, at 1: Hi, thanks for this post. Is there any cheap and good quality stereo amplifier for headphones? The only change I made was a suggestion elsewhere to bump the capacitor from Pin 3 of the lm to the ground to a 50uF capacitor to help reduce more hum on the output. Notify me of follow-up comments by email. Arslan on April 3, at Shafin on October 5, at 4: I am interested in recycling my old notebook speakers 2watts each to make a usb driven amplifier with 2.

Bandid on October 12, at 8: Hi Alex, this amp works great for headphones… Since the diagrams in the post are mono amps, all you need to do is build two amps, one for the right channel and one for the left channel. Could u please send me an updated schematic?

Decoupling means disconnecting two electronic circuit stages against cc from each other. Hariz on November 15, at My lm chip starte heating up once I had connected the cell — any idea why?!

There are better lmm386n-1 and circuits to use than the LM for that purpose. Cant seem to figure out what is wrong cos i followed the diagram exactly without success.


Hemant chaurasia on June 12, at The LM cannot amplify more than the input voltage, if you have a 1V input signal the output will max out at 5V. Hi, I am doing an audio amplifier but with 3 outputs instead of single output…so what should i add to make it work Reply. Notify me of new posts by email.

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

Can you please help in that input portion? Michael Hiltz on February 22, at 7: I have tried this circuit and it worked. Check out our tutorial on the TDA, it has about 12 watts output power: Naveed Hassan on February 19, at 7: Ola on June 24, at It should be required to do some things with this before graduating to a IC class D amp! DungFung on July 29, at 6: Your email address will not be published. Classified was meant to be class a and water energy was meant to be wasted energy Reply.

Then there is a 0. Hope this makes is clear, without a revised schematic. Bruno on April 27, at 4: I understood from your other tutorials that C2 and R1 act as low pass filter.
