Billy Amateo on September 23, at 6: Circuit Basics on March 8, at 9: I used the LMN-1, but the setup would be the same for each model, the main difference being the power output.

Igor on December 1, at 9: The minimum voltage rating is 4V, so it might not work. Hope you had fun experimenting with these amps as much as I did.

The datasheet has graphs that will tell you. Hoverboards UK on May 18, at 6: RickS on July 21, at I also want to add an FM radio on it. What is the load of the circuit? Naveed Hassan on February 19, at 7: Classified was meant to be class a and water energy was meant to be wasted energy Reply.


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:. I understood from your other tutorials that C2 and R1 act as low pass filter.

Thank you in advance. They work just as well and are better than a handfull of jumper wires….

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

Circuit Basics on May 25, at BTW the number sure do bring a lot of old memories back. You get a constant hum if you do and I have not yet found a dataeheet to fix this.

Algen on May 14, at 8: So the input signal will get oversteered fairly quick. Ryan on December 22, at 7: If your gain is set tothe range of volume is 0 to Dear Alex the dataasheet circuit u can use by connecting pin 1 and 8 with jumper works well with 3.

The only circuit diagrams I have are already included in the article.

Excellent tutorial I managed to make the first two today and will work on the final versions next. If I were you I would rebuild the entire circuit with all the components replaced including the chip and the speaker. Tuck datashert May 13, at 1: I used an 8 ohm speaker, but anything from 4 to 16 ohms will work.

A cool feature of the LM is the option to add an adjustable bass boost to the amplifier. With 9V and an 8 ohm speaker the power is to mW Reply. Simon Tay on September 12, at 5: I tested it and it worked! Circuit Basics on Dstasheet 8, at 8: DungFung on July 29, at 6: Abdelrahman Tarek El-Ruby on December 1, at 3: Thanks in advance for helping already getting far with building it.

Such PS is feeding both circuits in parallel.

It drives a pair of 8Ohm Onkyo home theater speakers with room filling sound.
