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 Voltage?
Load Voltage calculator uses Load Voltage = Input Voltage-Base Emitter Voltage to calculate the Load Voltage, Load Voltage is defined as the voltage developed at the load terminals of a power amplifier. Load Voltage is denoted by VL symbol.
How to calculate Load Voltage using this online calculator? To use this online calculator for Load Voltage, enter Input Voltage (Vin) & Base Emitter Voltage (Vbe) and hit the calculate button. Here is how the Load Voltage calculation can be explained with given input values -> 0.25 = 7.5-7.25.
