Hi, could you let me know what your output Amperage and Voltage is? Can you post the Schematics for these Circuits? Philip on May 21, at I just want to ask if this is an active or passive loudspeaker? Please send me the schematic diagram.
Arslan on April 3, at I started with the LM then the LM op amps so I am always pleased to see someone trying to make catasheet simple for the new folks! As an old Pensioner 72 just starting out in electronics I have completed my your first amplifier. Stereo Pots… Works fine with me. The LM cannot amplify more than the datwsheet voltage, if you have datasheett 1V input signal the output will max out at 5V.
Thank you very much for sharing. Jithin George on November 17, at 4: A cool feature of the LM is the option to add an adjustable bass boost to the amplifier. Bandid on October 12, at 8: I have been trying to have the parts list sent to my e-mail address but to no avail.
I may just try to use a plastic adtasheet, but I put a lot of effort into setting up the Altoids tin just right. Anything 16V and over will work fine with a 9V supply Reply. Is is possible to use more than 9v for example 12v with the two latter circuits just as is or is there anything that needs to be changed?
Build a Great Sounding Audio Amplifier (with Bass Boost) from the LM386
I have tested it and I see indeed that it works as a low pass filter. Hi, When you added the bass bost control, can you add a speaker that gives bass only, something much more like a sub-woofer???
I also want to add an FM radio on it. Can u please dtasheet what kind of speaker to use? If you were to put this in a copper layout what would it look like.
Rajesh on September 22, at 4: Aniket Sarkar on March 19, at Sir I want to use a condenser microphone as my input instead of datasehet audio jack.
I cant find the 0. That was a mistake, the diagrams have been updated now Reply.

Roy Hammond on July 17, at 6: Datashee used a 4 ohm speaker Reply. Jefferson Yagdulas on March 3, at 3: Roi Magadia on September 29, at 4: Alex Dtaasheet on March 26, at 8: I have tried others circuit regariding this LM and this is the best circuit i can say but just wondering can i use a 3.
We just published a tutorial on the TDA which has an output power of around 7 to 12 Watts: Circuit Basics on August 22, at 2: And a really helpful video btw! Yes, we just recently published a few other tutorials on some more powerful amps.
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 lm386-n1 one for the left channel. Will you be kind enough to email ratasheet to me? They work just as well and are better than a handfull of jumper wires… Reply.
WillW on December 18, at 6: The actual output power you get will depend on your supply voltage and datashet impedance. Shafin on October 5, at 4: Thanks for easy homemade circuts i love this siteReply. I built this according to the information above, and double-checked the schematics in the LM datasheet, but for some reason I do not get a change in volume when adjusting the volume potentiometer.
Google classified a amplifier and use one of the tip datasueet transistor. Suman Dutta on August 12, at 6: Will on December 19, at 7: Thanks btw for this great article and all the others!
