Amplifier with TDA7235

Low Power Audio Amplifier Circuits

Low power audio amplifiers. There are a multitude of low power amplifiers using integrated circuits, I will show some quite common, easy to make and generally low cost. Most of these amplifiers are used by televisions, test and measurement equipment, old modems, etc. At present there is talk of sound equipment of “10,000 Watts PMPO” […]

5W stero Amplifier Circuit

5W Stereo Audio Amplifier

In this article we are going to show you how you can build a 5W stereo audio amplifier using TEA 2025 IC. We have used two potentiometers for left and right volume controls. It has power output is 2.5 watts on the left and right channels. It used 9 to 12 volts power supply for […]

IC 4440 Amplifier Circuit

In this project we are going to built a simple IC 4440 amplifier circuit but the output is very nice and very high. It is 12 volts audio amplifier using is LM4440 IC 19 Watts amplifier. We have designed it without PCB and used few capacitors with it. we can use it in car audio […]

Class A power amplifier circuit

Two Transistor Amplifier

For most systems single transistor amplifier does not provide sufficient gain or output impedance matching. The solution is only to combine multiple stages of amplification. In this amplifier circuit we are going to shows a simple two transistor amplifier. In the single transistor amplifier circuit we have made a very simple amplifier with one transistor, […]

Single Transistor Amplifier

Single Transistor Amplifier Circuit

An audio amplifier is a device which multiply an applied input signal amplitude to a level that may be much higher than the input signal. The input is given in the form of an audio or a music. The amplifiers are classified into classes like class A, class B, class AB, class C and class […]
