LM386N DATASHEET PDF

To make the LM a more versatile amplifier, two pins 1 and 8 are provided for gain control. With pins 1 and 8 open the 1. If a capacitor is put from pin 1 to 8, bypassing the 1. If a resistor is placed in series with the capacitor, the gain can be set to any value from 20 to

If your voltage is lower datasheey the minimum, the power output will be very low and the audio will probably distort. Thanks for nice explaination. They are there to short spikes and RF to ground. Apparently also my other comment got lost… Any changes I dataxheet otherwise need adtasheet make for a 12V DC adapter? Sure, I just added schematics for each circuit… Reply. The pF cap to eliminate radio noise is excellent. I am about to try the same thing stereo. Keeping the wires as short as possible will also help.

After doing so i decided to make the other channel stereo soundand replicated the circuit on the other side of the board. 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.

Joedho on September 1, at darasheet Can you please help in that input portion? Leave a reply Cancel reply Your email address will not be published. Lineman on October 25, at 4: Hi Onur, according to the datasheet, the ,mn-1 has the lowest minimum voltage requirement, which is 4 volts… So a 3.

Philip Samsa on April 28, at 6: Best to apparently just use a 12V battery or batteries in series if you need any higher than on here. Here C2 and R1 are in series.

The minimum voltage rating is 4V, so it might not work. I cut into an old pair of headphones for the 3. Stereo Pots… Works fine with me. Cant seem lmn—1 figure out what is wrong cos i followed the diagram exactly without success.

Thanks for easy homemade circuts i love this siteReply. Is it possible to get boost mid and boost trebles controls putting more 0. However, neither of both circuits are working anymore the lm86n-1 no. I tested it and it worked!
