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 […]

LM386 Audio Amplifier Circuit

Amplifier Using LM386

In this article we are going to show you a simple LM386 audio amplifier circuit. Circuit diagram of the LM386 based audio amplifier is shown in the given below diagram and animated picture. It is built by using popular amplifier LM386 (IC). We have used 8-ohm speaker, one-watt speaker, four electrolyte capacitors. We have used […]

Two Transistor Amplifier

Class A power amplifier circuit

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 Circuit

single transistor amplifier

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 […]
