This article lists various types of audio amplifier circuits using Mosfet. We have tested all these circuits in our lab and we found all of them performing satisfactorily. What is a Mosfet Amplifier? Mosfet is a 3 terminal semiconductor device used in a wide range of electronic circuits. It works like a JFET but has […]
19 Watts Simple Amplifier Circuit This is a 19-watt simple amplifier circuit diagram using IC LA4440 from Sanyo. It uses very fewer components other than the IC LA4440. A very high-quality circuit with respect to its cost and ideal for beginners. Here IC LA 4440 is wired as a bridge amplifier to deliver a 19
What is a sound level meter? A sound level meter is handy equipment used to display sound levels. There are wide ranges of these devices; some show a digital numerical output of how many decibels of sound are created while some other shows a bar graph indicator (the decibel meter you see in mission impossible
In this project, let’s learn about a simple Stereo Amplifier Circuit. This simple circuit is designed using 4 class B audio amplifier IC’s from Philips – namely TDA1554. Amplifier circuits are usually a pain to design, as you’ve to factor many elements into consideration. The Design of Stereo Amplifier Circuit Here is the circuit diagram of
All audio amplifiers have some mechanism to increase and decrease volume. Most such mechanisms involve mechanical parts like a potentiometer. Here this project is to create an audio controller that works digitally. This is a very simple project which uses two switches and an IC to electronically control the audio output from an amplifier. Digital
