TL074 is a JFET-input quad operational amplifier monolithic integrated circuit. This op-amp IC contains four OP-AMPs. It consists of high voltage junction field-effect transistors (JFETs) and Bi-polar junction transistors (BJTs). In addition, Input bias and bias currents are low. On the contrary, the slew rate is very high. TL074 is highly recommended for audio pre-amplification as it has low noise and low harmonic distortion. Most importantly, input offset adjustment is possible externally making use of the specific circuits. Furthermore, frequency compensation is possible internally and the operation of TL074 is rendered as latch-up-free. TL071 and TL072 are the single and dual OP-AMP versions of the TL07X family.

How to Use
We need two power supplies to operate TL074. The terminals or the pins used are pins no. 4 and 11. Pin no 4 is for positive power supply. Pin no 11 is for negative power supply. For the first OP-AMP, inverting input is applied at pin 2. Non-inverting is a pin 3 for the second operational amplifier. The output of the first OP-AMP is obtained at pin no. 1.
- For the second OP-AMP, inverting input is applied at the pin. No 6 and non-inverting at pin no. 5.The output of the second OP-AMP is obtained at pin no. 7.
- For the third OP-AMP, inverting input is applied at the pin. No 9 and non-inverting at pin no. 10. The output of the third OP-AMP is obtained at pin no. 8.
- For the fourth OP-AMP, inverting input is applied at the pin. No 13 and non-inverting at pin no. 12. The output of the fourth OP-AMP is obtained at pin no. 14.
