Here, I configured the audio amplifier in bridge mode for getting 20 W + 20W powerful audio output. Therefore, we need 2 ICs for making stereo and 2 copies of the same circuit which we will discuss in the circuit diagram section.

The main difference between those two modes of configuration is in stereo mode a single IC can drive a maximum of 6W + 6W two speakers that mean only 12 watts of load but in the bridge mode configuration, you will get 19W audio output from a single IC for a single speaker. It has dual enabling modes, namely the stereo mode, and bridge mode. The IC can be used as a mono audio amplifier or as a stereo dual-channel audio amplifier. LA4440 ICīefore starting to build this amplifier, let's understand more about the LA4440 Power Amplifier IC to know about its technical specifications so that we can design our amplifier efficiently. As shown below the LA4440 is a 14-pin Linear Audio Amplifier IC developed by SANYO. You can also check them out if your requirement is different. We have previously built a lot of Audio Amplifier circuits ranging from small 10W amplifiers to heavy 100W Power amplifier using different classes of the Power amplifier to suit various applications. Also, the audio input for our amplifier board can either be provided directly from an audio jack or wirelessly using Bluetooth. The circuit will have two LS4440 amplifiers ICs and will be able to drive two 20W Speakers (20W+20W) with volume, bass and treble control. Hence in this article, we will learn how to build a High-Power Stereo Audio Amplifier using the LS4440 Audio Amplifier IC. Home Theatre and Car Amplifier Systems which operate on 12V. The IC is known for its high power, easy availability and cheap price which makes it popular among The LA4440 is a very popular dual-channel audio amplifier commonly used to build high power audio amplifiers.
