What kind of power draw does a LM386 have?
LM386 is a low voltage power amplifier with an inactive power draw of 24mW, which makes it suitable for battery controlled applications. The most common package for LM386 is an 8 – pin DIP.
How many times does a LM386 increase the potential?
They take an input potential (voltage) and produce an output potential that’s tens, hundreds, or thousands of times the magnitude of the input potential. In an amplifier circuit, the LM386 takes an audio input signal and increases its potential anywhere from 20 to 200 times.
What kind of resistor do I need for LM386?
Since LM386 is a Mono Audio Amplifier, we need to connect either the Left audio or the Right Audio from the source along with ground. Alternatively, both the channels can be combined to produce a mono channel using appropriate resistors. If we want to control the level of the input, we need to connect a 10 KΩ Potentiometer at the input.
Is the LM386 IC a good audio amplifier?
There are many Audio Amplifier Circuits designed using LM386 IC. The main problem with these circuits is noise and interference. The noise from the Amplifier Circuit designed in this project is considerably less and if designed on a proper circuit board, this will make a great Audio Amplifier.
