In this project i will show you why a class ab amplifier is pretty inefficient and how a class d amplifier on the other hand improves this efficiency at the end i. This lm386 based audio amplifier is built around the amplifier lm386, an 8-ohm, one-watt speaker (ls1), four capacitors and a few other components. Browse through a total of 47 audio amplifier circuits and projects tpa3122d2 class d audio amplifier application: make your own computer speaker system this simple and inexpensive project will let you set up a low voltage audio amplifier tda2005 is a class b dual audio power amplifier specifically designed for car radio applications.
The ds2 line offers products with high feature-sets, impressive value and outstanding sound with a very detailed and natural sound that convinces with a big and airy sound stage.
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 this is the best project with an lm386 i have seen in the web, for many reasons – very professional and cool, and yet easy for newbies. Lm386 basics the lm386 is quite a versatile chip only a couple resistors and capacitors are needed to make a working audio amplifier the chip has options for gain control and bass boost, and it can also be turned into an oscillator capable of outputting sine waves or square waves. Project 1 i’d like to share this simple audio amplifier circuit with you as the first project in the website i built the model unit conservatively using what's available in the parts bin: 2 pairs of 2sc5200 and 2sa1943 or 2sc5242 and 2sa1962.
