PNP and NPN Darlington Pair Transistor Amplifier Circuits These transistors are found in different types of applications such as power regulators, motor controllers, audio amplifiers, etc. Many opto isolator circuits are made with Darlington transistors to have high current capacity at the output stage. Simple Audio amplifier Using Transistors Stack Exchange I would like to build a simple audio amplifier using transistors. I know there are IC designs specifically for the task. But i want to use transistors so i can learn how to use them for amplification. How would I go about designing an audio amplifier from just discrete components. The Simplest Audio Amplifier Circuit Diagram 2.5W * 2 Stereo Amplifier. The amplifier circuit diagram shows a 2.5W * 2 stereo amplifier. You can also make a 5W mono amplifier out of it. (Check out the TEA2025 datasheet for more information on that) On the input side, you should use a dual potentiometer. A dual potmeter allows you to connect both left and right channel on one potentiometer. Transistor The first discrete transistor audio amplifiers barely supplied a few hundred milliwatts, but power and audio fidelity gradually increased as better transistors became available and amplifier architecture evolved. Modern transistor audio amplifiers of up to a few hundred watts are common and relatively inexpensive. parison with vacuum tubes Amplifier The practical amplifier circuit shown above could be the basis for a moderate power audio amplifier. It features a typical (though substantially simplified) design as found in modern amplifiers, with a class AB push–pull output stage, and uses some overall negative feedback. Bipolar transistors are shown, but this design would also be ...
