Sure, I just added schematics for each circuit… Reply. You can ignore this potentiometer if you want to operate in full volume. Has someone an circuit for this?

LM (M) Audio Amplifier | NightFire Electronics LLC

Hoping to be of some help. R on June 26, at Next one I build will be with the 1 watt output LM As a tester for a particular system. I used 5v USB power datashdet it. Maybe 10uf on input and uf on output. Billy Amateo on September 22, at 6: Only negative thing is when I connect the bass boost that there is a lot of dB loss.

LM386 (M-82) Audio Amplifier

Mike on September 13, at 7: Thanks yaboc, glad you liked it. Hi, great tutorial and very informative thank you! The 10k resistor is added in series with the audio signal to act as a volume control.

Segway on January 31, at lm3886n Is it possible to get boost mid and boost trebles controls putting more 0.

Cant seem to figure out what is wrong cos i followed the diagram exactly without success Reply. Robert on February 8, at 2: Thanks for nice explaination.

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

Yes, you can use a 3. Notify me of new posts by email. Kennynva on January 4, at 4: BTW the number sure do bring a lot of old memories back. The actual output power you datashete will depend on your supply voltage and speaker impedance.

Roi Magadia on Daatsheet 29, at 4: So the input signal will get oversteered fairly quick. The only circuit diagrams I have are already included in the article. Sir, what kind of speaker we should use. It does sound a bit better.

LM Audio Amplifier IC Pinout, Features, Circuit & Datasheet

I took a lot of time to datashret Reply. David Bliss on October 22, at 7: 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:.

Dear Alex the same circuit u can use by connecting pin 1 and 8 with jumper works well with 3.

The bass boost is basically just a low pass filter, and it removes most of the noise not taken out by the decoupling capacitors. Shafin on October 5, at 4: Kev on April 22, at 1: Can u please tell what kind of speaker to use?

R D Biggs on November 20, at 9: Risks are eventual continuous current coming from the source blows the LM IC, or worst case a problem with this amplifier datashwet, causing continuous current flowing to the source, makeing hot-dogs of your connected smart phone.

I suggest building figure 10 in the St micro datasheet. Aravind on March 31, at
