What is LM386 IC?

In this article, I would like to explain what is LM386 IC and its applications. Also covers LM386 Pinout and Datasheet in this tutorial. All electronic circuit projects cover on this website ie. Circuits99.com.

The LM386 is a dual comparator IC it can convert analog to digital. It has two comparator inputs which are one positive and another is a negative signal. One positive power supply input and the other is ground. The LM386 IC is used in devices such as sensors, displays, and actuators, where it is important to have an analog signal on only one of the comparator inputs. The other input is used to allow a digital signal to be output on the output pin.

The LM339 is an integrated circuit that is used in a variety of different applications. It contains both an op-amp and a voltage regulator. Which are often combined into a single chip. The LM339 is designed to work at voltages between 1.8 and 5 volts and can handle currents of up to 2.1 Amps. It is often used as a voltage regulator in power supplies, as it is able to handle large amounts of current without overheating or failing.

How does the LM386 circuit work?
The working of the circuit is very straightforward as all the work is done by the LM386 IC itself.
Why use an LM386 in an amplifier?
The LM386 takes an audio input signal and increases its potential anywhere from 20 to 200 times.
