4 kwi 2015 · Find out how to build a great sounding audio amplifier (with bass boost) from the LM386 IC, and learn what makes this amplifier sound better than the rest.
20 maj 2023 · In this guide, we will learn about the LM386 Low Voltage Audio Power Amplifier IC basics, features, circuit, working, pins configuration & Applications. You can go through the Op-Amp IC 741 & also LM358 Dual Op-Amp IC to learn more about the operational amplifier. Features and Specifications
The LM386 is a power amplifier designed for use in low volt- age consumer applications. The gain is internally set to 20 to keep external part count low, but the addition of an external resistor and capacitor between pins 1 and 8 will increase the gain to any value from 20 to 200.
A very basic commonly used LM386 circuit is shown below. The IC is powered using the pin 6 (typically 5 or 9V) and the ground pin 4 is connected to the ground. The inverting pin (pin 2) is normally grounded and the Non-inverting pin (pin 3) is provided with the Audio signal.
Step 1: LM386 101. A good place to start is the official datasheet (PDF) where you can get all the technical information you need. But I'll go over the basics here.
