The TL072 is an operational amplifier with high input voltage junction field-effect transistors that have low noise and a high slew rate. Additionally, the input bias and offset current values are lower. There are two operational amplifiers included in this dual-operational amplifier. Due to decreased harmonic distortion and low noise, it is mostly favored for high-accuracy circuits. Additionally, it is preferred for circuits that require audio pre-amplification.

Description:

A high-speed Junction Field Effect Transistor is essentially what TL 072 is (JFET). It is additionally referred to as a dual-operating amplifier. In its case, it has a high voltage JFET and a bipolar transistor. Low offset current, high slew rates, low input voltage, low offset temperature coefficient, and other key characteristics of the TL-072 are included. Low power consumption, low noise, a common mode input voltage range that includes Vcc, latch-up-free operation, etc. are some of the primary features that may be present. Oscilloscopes, solar inverters, AC inverters and VF drives, audio mixers, Uninterruptible Power Supplies (UPS), and many other devices are among the many applications for TL072.

Principle of Work:

Op amps are essentially multistage amplifiers with extremely intricate connections between their various amplifier stages. Numerous transistors, FETs, and resistors make up its internal circuit. All of this takes up very little room. Therefore, it is available in the form of an Integrated Circuit (IC) and is packaged in a compact box. An amplifier that can be set up to carry out different operations, such as amplification, subtraction, differentiation, addition, and integration, is referred to as a "op amp." Two input terminals and one output terminal compensate an op-amp. There are two voltage supply terminals on the op-amp as well. The differential input is made up of two input terminals. We refer to the terminal of the operational amplifier denoted by a negative (-) sign as the inverting terminal and the terminal denoted by a positive (+) sign as the non-inverting terminal. The amplified output signal is 180 degrees out of phase with respect to the applied input signal if an input signal is supplied to the inverting terminal (-). The output signal will be in phase, or without phase shift with respect to the input signal, if we apply an input signal to the non-inverting terminal (+).

Circuit:

 Amplifying a signal from a sensor when it has an offset voltage

Many common sensors will produce a voltage that does not "sit" on the 0V rail

The green signal is too small (say 0.04V) to measure with any accuracy; however, by amplifying it by 100 we get a signal of around 0.04*100 = 4V that can be measured.

However, the signal on the blue line is small but has a dc offset of about 2.5V; multiplying that by 100 gives a 25V signal that still can't be measured. If the DIFFERENCE between the signal and a fixed offset (the orange line) is amplified it gives a nicely measurable signal. The amplification (or gain) and offset can be adjusted to suit your particular sensor.

Comparisons:

The TL080 series has been designed as general-purpose op amps. It combines a low-distortion bipolar output stage with the advantages of JFET input transistors (low bias current and high input impedance). The 11070 series is similar to the general-purpose TL080 series but with low noise characteristics. This makes members of this series ideal for use in high-performance, low-noise applications. The TL060 series is again similar to the TL080 series but incorporates a trade-off of slew rate for minimal power dissipation. A variation of this is the TL066 which offers a programmable power option. These devices were designed for battery operation and other applications requiring a minimum of power dissipation combined with the performance characteristics of a BIFET operational amplifier.
