Darlington Pair Audio Amplifier. In order to achieve some increase in the overall values of circuit current gain and input impedance two transistors are connected as shown in the following circuit diagram which is known as darlington configuration. Hence this pair is also referred to as super alpha circuit.
The output transistors do not increase the size of the audio signal. The compound pair needs only 625mv vs. They need to be rated at 75 watts or higher 5 amps for higher and 80 volts or higher.
In these circuits the darlington pair may be a single device containing the integrated darlington or they can be circuits that are made from the discrete transistors.
2 a voltage gain of about 1 and a low input impedance. Circuits used in association with light sensor audio amplifiers and power supplies are some common examples of circuits using darlington pair transistors. The interconnection between the pair provides the current produced at the emitter terminal acts as the input current for the terminal base of the next transistor. Darlington complementary is the basic order in how the output stage of an amplifier is taught.
