It is also used in video applications such as video amplifiers, video signal amplification and video switching. Additionally, it can be used in other applications such as active filters, instrumentation amplifiers, motor controls, transducers and a variety of other consumer electronics applications.

Working Principle

The working principle of the TL072CPWRG4 is based on the differential amplifier configuration, which is a circuit that amplifies the difference between two input signals. It consists of three transistors and six resistors, which are connected in a particular way and form the differential amplifier. The differential amplifier is fed with two input signals, one at each of its non-inverting inputs, and then the output signal is amplified and received at the output terminal. The differential amplifier eliminates common mode noise, which is generated by any non-ideal external components or sources, including power supply voltage fluctuations.

The differential amplifier configuration is followed by an unity gain voltage follower, which is controlled by the amplifiers gain potentiometer. The amplifier\'s gain can be adjusted by varying the resistance of the voltage follower\'s potentiometer and thus the output voltage of the amplifier is adjusted. The TL072CPWRG4 also includes additional features like overload protection and thermal overload protection, which make it more suitable for use in a wide range of applications.
