The LM is a power amplifier designed for use in low volt- .. Reproduction of TI information in TI data books or data sheets is permissible only if reproduction. LM is a power amplifier designed for use in low voltage consumer applications. The gain is internally set to 20 to keep external part count low, but.

I have 2 questions….
I am doing so to attempt to convert from 9v to 12v. But yet I have a few questions D: Subscribe Subscribe to get new tutorials sent straight to your inbox! Mayank on July 26, at 5: What is the output of the circuit? Boss, this is the best circuit i have ever seen.
Ryan on December 22, at 7: I am an undergraduate from Ghana and am working on a similar circuit. Sir I have 4 ohm 2speakers so what amplifier I should use Reply. I imagine it would be the same as an opamp. You can check the datasheet, the output power depends on your power supply voltage and the impedance of your speakers.
Rajesh on September 22, at 4: I started with the LM then the LM op amps so I am always pleased to see someone trying to make this simple for the new folks! The pin 1 and pin 8 are used to set the gain of the Amplifier.
I use a 12V supply and a pot meter dataeheet attenuate the input signal to something below 0. They work just as well and dattasheet better than a handfull of jumper wires… Reply.
The pF capacitor is shown wrong in the diagram. I have tested it and I see indeed that it works as a low pass filter.
Marius on April 3, at Victor Faucheret on April 24, at 5: Billy Amateo on September 23, at 6: Hi, I am doing an audio amplifier but with 3 outputs instead of single output…so what should i add to make it work. I really enjoyed this tutorial and this would really help me a lot in my experiments. Hi Sanjeev, double check to make sure lm386 is connected properly, and the polarity of the electrolytic capacitors are correct… Reply.
Thanks in advance for helping already getting far with building it. Please answer it Reply.
dataheet Thempleton Aart on October 12, at 4: Hi, could you let me know what your output Amperage and Voltage is? Check out these articles: If you were to put this in a copper layout what would it look like.

R on June 26, at And what are the voltages of capacitor that you used? Tem como fazer stereo?
Will you be kind enough to email it to me?
