STEP 0: Pre-Calculation Summary

Formula Used

Power Output Capability Factor = (Maximum Output Power)/(Peak Drain Voltage*Peak Drain Current)
CF = (P_max)/(V_d*I_peak)
This formula uses 4 Variables

Variables Used

Power Output Capability Factor - Power Output Capability Factor is the ratio of the average power output over a specified period of time to the maximum possible electrical energy output over that period.
Maximum Output Power - (Measured in Watt) - Maximum Output Power is defined as the highest value power obtained at the output of an amplifier.
Peak Drain Voltage - (Measured in Volt) - Peak Drain Voltage represents the maximum voltage that can be applied across the drain and source terminals of a power transistor under turn-off conditions.
Peak Drain Current - (Measured in Ampere) - Peak Drain Current indicates the highest current-carrying capacity of a single silicon unit, without considering the limitations of the package and safe operation area.

STEP 1: Convert Input(s) to Base Unit

Maximum Output Power: 1300 Milliwatt --> 1.3 Watt (Check conversion here)
Peak Drain Voltage: 15.6 Volt --> 15.6 Volt No Conversion Required
Peak Drain Current: 90.99 Milliampere --> 0.09099 Ampere (Check conversion here)

STEP 2: Evaluate Formula

Substituting Input Values in Formula

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.
