In the audio segment: output voltage = A0 (E1-E2), where A0 is the low-frequency open-loop gain of the operational amplifier (such as 100dB, which is 100000 times), E1 is the input signal voltage at the non-inverting terminal, and E2 is the input signal voltage at the inverting terminal.

operational amplifiers is the very high gain achieved at the output. In general, gain is calculated as Vgain = Vout/Vin, a ratio of the output voltage to the input voltage. An op-amp amplifies the difference between one input and the other, while neither individual input is itself amplified. The output is positive if the non-inverting input is more

An operational amplifier commonly known as op-amp is a two-input single-output differential voltage amplifier which is characterized by high gain, high input impedance and low output impedance. The operational amplifier is called so because it has its origins in analog computers, and was mainly used to perform mathematical operations.

An op-amp consists of differential amplifier (s), a level translator and an output stage. A differential amplifier is present at the input stage of an op-amp and hence an op-amp consists of two input terminals. One of those terminals is called as the inverting terminal and the other one is called as the non-inverting terminal.

This process of amplification is utilized in the various domains where an electical signal is converted to an acoustic signal. This type of amplifiers is known as audio amplifiers. Any circuit which processes the audio signal has the audio amplifier both at the input and also at the output. For example, if a microphone receives a sound wave input signal it need a pre …
