![]() The IC is powered using pin 6 directly to the positive power supply and the ground pin 4 is directly connected to the ground. Here is a simple circuit schematic is given below. ![]() So, it is a low-cost audio amplifier IC which can be powered using a battery and also a portable device to drive an 8 Ω speaker then this IC might be the right choice for you. The IC also comes with an 8 pin PDIP package and requires very fewer components to work. We can use volume control and treble control in this circuit. It can easily drive an 8 Ω speaker or two 4 Ω speakers. The IC consumes very little power, and it can be operated by a 9V battery. The LM386 is a low power audio frequency amplifier which is very commonly used in small audio amplifier circuit project. In this tutorial, I will show you how to make an LM386 audio amplifier circuit. ![]()
