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 […]

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, […]
