If the value of R2 and R3 is placed too high then the noise will increase and if it is too low then the noise will be lower, but it may increase distortion as the load on IC gets high. R2 and R3 are negative feedback resistors, used for measuring the output signal. R1 is used for impedance balancing, which helps in getting low distortion. We can increase the value of resistor R4 due to having high input impedance. 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.
