Hi Guys....
I am new to these forums so i hope i have this post in the right section, i just built a FM receiver with a LM386 to amplify my signal, i had a problem with it making a terrible squealing sound, i found a circuit for an LM386 amplifier and it showed extra capacitors added, one...
Hey everyone,
I had this part laying around. I don't know where I got it from, but I don't know which manufacturer has this logo. Can anyone help me identify the mfr?
It's an LM386.
Thanks!
I have an LM386 and a 3w 4 Ohm speaker, and I've tried every possible schematic, and nothing seems to work. The sound quality is poor when I make the speaker audible, by turning the volume up. What should I do?
I currently made a module to my project which isn't quite functioning correctly. It's 4 distinct parts on one board. The radio I/O, the two independent sound amplifiers out of the LM386's and the RFID card reader.
This is the circuit:
The actual inverter IC I used is 74HCT04 because it...
Hello everyone,
A brother from my hometown told me to make a mini amplifier that can pull the power out from a USB charger(or PC USB).
I happened to working on a logic gate IC and burned the IC while using a USB(power bank) charger. I want to know is it safe to use a 5V-1A charger to power the...
Hey guys
I just uploaded my tutorial on how to build a simple audio amplifier using an LM386 chip. When using the maximum supply voltage it can reach a power output of roughly 1 watt. Hope you find it useful.
Schematic <Mod edit: If you have something to share, please post it here. Do not...
