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 load power of class A output stage?
Average load power of class A output stage calculator uses average_load_power = (Peak Voltage/(sqrt(2))^2)/Load resistance to calculate the Average load power, The Average load power of class A output stage formula is defined as the average power consumed by the load in a given period, usually, a day or a month. It also represents the average power generated by the power station during the same period (also neglecting transmission losses). Average load power and is denoted by P_{L} symbol.
How to calculate Average load power of class A output stage using this online calculator? To use this online calculator for Average load power of class A output stage, enter Peak Voltage (V_{m}) and Load resistance (Rl) and hit the calculate button. Here is how the Average load power of class A output stage calculation can be explained with given input values -> 0.005 = (10/(sqrt(2))^2)/1000.
