What is class A output stage? Where are class A amplifiers used?
A Class A amplifier stage passes the same load current even when no input signal is applied so large heatsinks are needed for the output transistors. These types of devices are basically two transistors within a single package, one small “pilot” transistor and another larger “switching” transistor.
The Class A Amplifier more suitable for outdoor musical systems, since the transistor reproduces the entire audio waveform without ever cutting off. As a result, the sound is very clear and more linear, that is, it contains much lower levels of distortion.
How to Calculate Load power of an output stage?
Load power of an output stage calculator uses load_power = Supply Power*Power-conversion efficiency to calculate the Load Power, The Load power of an output stage formula is defined as the part of the output of an electric power plant used for the operation of motors or heating devices. Load Power and is denoted by PL symbol.
How to calculate Load power of an output stage using this online calculator? To use this online calculator for Load power of an output stage, enter Supply Power (P_{s}) and Power-conversion efficiency (η) and hit the calculate button. Here is how the Load power of an output stage calculation can be explained with given input values -> 40000 = 500*80.
