The class AB push-pull output circuit is slightly less efficient than class B because it uses a small quiescent current flowing, to bias the transistors just above cut off as shown in Fig. 5.5.1, but the crossover distortion created by the non-linear section of the transistor's input characteristic curve, near to cut off in class B is overcome.Class AB, 125W Audio Amplifier This circuit uses the push-pull amplification output using the transistors SC5200 and SA1940 which are complementary transistors. The power supply should be symmetrical with + 45V and -45V. 125W Audio Amplifier Schematics... The trouble is, an opamp can't supply any serious power to a load but, in conjunction with a class B amplifier it can. Because, theoretically, an op amp has infinite open loop gain, when the loop is closed around a class B push pull stage it can compensate for the class B crossover inadequacies. Class D amplifiers are very different than a class ab amplifier, which is more traditional. Little signal in, big signal out. It looks at the input signal, output signal for identical and every step of the way, it is making a larger identical signal.
