TL081 JFET Input Op-Amp

Contents hide

TL081 combines two cutting-edge linear technologies on a single monolithic integrated circuit. Each internally compensated operational amplifier has well-matched high voltage JFET input devices for low input offset voltage. The IC has a range of working conditions a wide range of working voltages and possesses direct interfacing capability with almost every PMOS, CMOS, and NMOS device. Moreover, the IC offers a wide array of features such as high noise immunity, ESD barring/reduction, and exceptionally low power dissipation. TL081 operates over a wide range of commercial, industrial, and military temperature ranges

Operational Amplifier

An operational amplifier is one of the basic building blocks for analog circuits, An operational amplifier takes in differential voltage input and produces a single-ended voltage output. The basic purpose of employing an operational amplifier in an analog circuit is to perform the function of signal amplification: The process of boosting an electrical signal of low strength to a level of higher amplitude.

Op-amps also function as a filter of the input signal; meaning that, an operational amplifier is able to extract the signal with the target frequency. Op-amps can be divided into two fundamental parts:

Precision Op-amps
Differential Op-amps
