Audio Amplifier Gain Calculator

An engineer s design requires 100 mw of rms output power to be driven into his 16 ω speaker.

Audio amplifier gain calculator. An op amp is a high gain differential amplifier module that forms the central component in a variety of useful straightforward amplifier circuits. Amplifier conversion gain loss gain means signal strength or amplification in audio we use only voltage amplification. Designing with op amps is far simpler than creating customized amplifiers from discrete components and the resulting circuits are easily fine tuned according to the needs of the application. The audio amplifier runs off a 5 v supply and is driven by an audio codec that has a maximum.

Use the first calculator or if you want to know how loud a given amplifier will be use the second calculator. Equation used to calculate the data. This calculation will give you the ratio in decibels between two power values. Because amplifiers have the ability to increase the magnitude of an input signal it is useful to be able to rate an amplifier s amplifying ability in terms of an output input ratio.

Enter any two values and press calculate for the remaining value. In electronics gain is a measure of the ability of a two port circuit often an amplifier to increase the power or amplitude of a signal from the input to the output port by adding energy converted from some power supply to the signal. In the calculator below first input the distance from the speaker. Decibel calculator for audio voltage increase amplifier power and volume calculator.

It tells how many times the output voltage will be than the input voltage. Inverting op amp gain calculator calculates the gain of inverting op amp according to the input resistor r in and feedback resistor r f the gain indicates the factor by which the output voltage is amplified i e.

The technical term for an amplifier s output input magnitude ratio is gain as a ratio of equal units power out power in voltage out voltage in or current out current in gain is. For example you can calculate the difference in db between two amplifiers with different power output specifications. The amplification factor also called gain is the extent to which an active device boosts the strength of a signal.

Sloa105 4 calculating gain for audio amplifiers 2 3 se example questions. It is usually defined as the mean ratio of the signal amplitude or power at the output port to the amplitude or power at the input port. This amplifier power and volume calculator will help you understand that doubling the amplifier power does not double the sound pressure level spl or the perceived loudness.
