Use the C4 bigger.

With 9V and an 8 ohm speaker the power is to mW Reply. Consent to store personal information: Bonn Joemar Oleo Cabrera on July 27, at I need to break-in my new subs. Gert on September 25, at 8: Bruno on April 27, at 4: You need to do the one that is 15 watts so we can really jam out. Class a amps have more potential in terms of audio quality but Are harder to design due to having to properly bias the transistor.

What is the voltages of the electrolytic capacitors? Aravind on March 31, at A cool feature of the LM is the option to add an adjustable bass boost to the amplifier.

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

Can you please help in that input portion? I have updated all of the diagrams so that they all run from pin 4.

Note datashete anyone working on this: This is the best project with an LM I have seen in the Web, for many reasons — very professional and cool, and yet easy for newbies. The actual output power you get will depend on your supply voltage and speaker impedance. Tom on July 14, at Rahil Gada on Daatasheet 22, at Such PS is feeding both circuits in parallel. So the lmn-4 om386n-1 make a 2w amplifier. Steven Scheerlinck on November 25, at 7: The LM is a type of operational amplifier Op-Amp.

Email me new tutorials and very occasional promotional stuff: Hi Onur, according to the datasheet, the LMN-1 has the datashert minimum voltage requirement, which is 4 volts… So a 3. So the two negative wires would connect to the negative rail, and the two positive wires would connect to the negative side of the uF capacitor. NOME on December 30, at 1: How can I do it?? Could you tell me more about the theory here? R D Biggs on January 21, at 9: Circuit Basics on May 26, at 1: Thank you so much.

Cant seem to figure out what is wrong cos i followed the diagram exactly without success. I make this circuit. I just updated the images to show the positive side of the cap leading to pin 5. Is there any cheap and good quality stereo amplifier for headphones? Is it a mistake, or should there be a total of three caps connecting the positive rail to ground, of which two caps are 0. Norton Zig on June 24, at After doing so i decided to make the other channel stereo soundand replicated the circuit on the other side of the board.

This was my first ampmy first real circuit, and I did it with your video! Why do we need uF and 0.

Hi, Is it possible to get boost mid and boost trebles controls putting more 0. You can use another value for all of the capacitors, but they should around the same value Reply.

Then there is a 0. That amp was designed for car audio use, so it might be a better choice for you project… http: Can you share the PCB layout in this article?

Markus on August 19, at 8: Please let me know what modifications I need to apply to your circuit. Onno on December 1, at 1: In other words, there are two foils that are rolled together and the foil that ends up on the outside should be connected to the negative, because that relatively large area of metal foil picks up interference, which results in noise in dattasheet amp.

If I were you I would rebuild the entire circuit with all the components replaced including the chip and the speaker. I took a lot of time to see. Harold on May 26, at
