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 Average supply power of an output stage?
Average supply power of an output stage calculator uses average_supply_power = 2*Supply Voltage*Input Bias Current to calculate the Average supply power, The Average supply power of an output stage formula is defined as the average of the instantaneous power over one full cycle with the instantaneous power. Average supply power and is denoted by P_{s} symbol.
How to calculate Average supply power of an output stage using this online calculator? To use this online calculator for Average supply power of an output stage, enter Supply Voltage (V_{i}) and Input Bias Current (I_{B}) and hit the calculate button. Here is how the Average supply power of an output stage calculation can be explained with given input values -> 0.00024 = 2*12*1E-05.
