In the circuit, as the audio input is attached it will receive from the output with low noise and distortion. We can use this IC for audio pre-amplification or for better sound quality with having a low price of it with a high accuracy. So, can be used as a voltage comparator IC. It also compares the voltage like the other op-amp ICs do. The audio pre-amplification means for getting output audio with low noise, interference, distortion and also used for controlling the volume, bass and treble. TL072 is mainly used where high-accuracy is needed with respect to low harmonic and noise, as used for audio pre-amplification. It also used in the application of audio pre-amplification. This TL07x series come with low harmonic distortion and low noise which makes it fit for the use where high-accuracy needed. It’s a dual Op-amp IC means it contain two op-amp inside.

The Input bias and Offset currents is also low. These are high-voltage JFET-input operational amplifiers with low noise versions and high slew rate. Storage temperature ranges -65 to 150 ☌.Having infinite output short circuit duration.Having high slew rate (normally 13 V/μs).

Distortion of Harmonic is low (normally 0.003%).

Wide common-mode (up to VCC+) and differential voltage range.

Having two op-amp inside or called as dual op-amp IC.

Provided with the short circuit protection.

It has low power consumption, Input-bias currents and Offset currents.
