Product Summary

Low voltage got you down?

Let this power amplifier cater to your low voltage applications. The LM386 is set to have an internal gain of 20 to lower external part count. Addition of external resistor and capacitor between pins one and eight will increase the gain of any value up to 200.

  • For low voltage applications
  • Internal gain of 20 to lower external part count
  • Gain can be increased up to 200 with the addition of an external resistor and capacitor

        I am currently enrolled in engineering school and burned up the LM386 that came with my school parts kit. I was in the middle of a tough project and needed a replacement. The one I got at Radio Shack actually worked better than the one I got from school.

          Comments about RadioShack LM386 Low Voltage Audio Power Amplifier (8-Pin DIP):

          RS needs to show the datasheet! If radio shack did, it would be easy to connect according to National Semiconductor. Also there is a number just to the right of the dash. Different numbers tell different wattages. According to National Semiconductor,the LM386N-1 (the number I was talking about) powers an 8-ohm speaker with 0.325 watts. LM386N-3 powers an 8-ohm with 0.7 watts. And LM386N-4 powers a 32 ohm speaker with 1.0 watts! Thats like 4 WATTS of power for many speakers.

          So the next time you go to radioshack look in the compartment in the drawer that says LM386. Examine the chips carefully. Then when yon find the one that says: LM386N-4, you found the one that gives the most power out of the others. And you buy it for the price of the LM386N-1 which saves you some money and gives you more power then the lower power ones. Have fun looking around ;)

            built 2 very small portable guitar amps with this ic. requires very few other parts to opperate in basic use.**DOWNSIDE** once the battery(i used a standard 9V battery) drops below a certain voltage, it makes a very annoying buzz/hum sound.

                I used this with an ATMega328 microcontroller. The external gain control made it easy to adjust volume with the microcontroller. Overall, a nice way to add sound to a project.

                    This chip is great, but there is not enough power. Perfect for small applications, but if you want your music loud, this is not for you.

                          There isnt an schematic or diagram to be found? Poor documentation makes this part useless to beginners and DIY'ers with little experience.

                          I`ve used these for years for all kinds of things. (small sig. amps, ect.) I used one a few months ago as the heart of a audio mod. monitor. Just keep in mind that the n-1 sold here is the +5 vdc modal with an out. of 250mw. The n-3 version puts out the full 600mw or so off of +12vdc.
