Hello Friends, in this post I make a 38W stereo amplifier using LA4440 IC. This is a class AB amplifier. Which can deliver up to 19W RMS output per channel at 4Ω ±15V, Test frequency 1khz. This IC is very cheap and basic. So don't expect very good sound from this IC. This IC can give you a basic sound quality.
