The TL081 is a general purpose J-FET single operational amplifier manufactured by Texas Instruments. It has high open loop gain, high input impedance, low input current, low offset voltage, high conversion speed and good common mode rejection ratio, which is used in various signal amplification circuits.
The TL081 series (TL081, TL081A, TL081B) are high‑speed J‑FET input single operational amplifiers that combine well‑matched high‑voltage J‑FETs with bipolar transistors in a monolithic IC. They feature low input bias and offset currents, high slew rate, wide common‑mode range, and output short‑circuit protection.
The document provides detailed electrical characteristics, maximum ratings, package mechanical data for DIP and SO versions, typical application circuits, and performance graphs such as gain‑bandwidth product, total harmonic distortion, and noise voltage.
