TL071
Low noise JFET single operational amplifier
Features
■ Wide common-mode (up to VCC+) and differential voltage range
■ Low input bias and offset currenT ■ Low noise en = 15 nV/ √Hz (typ) ■ Output short-circuit protection ■ High input impedance JFET input stage ■ Low harmonic distortion: 0.01 % (typ) ■ Internal frequency compensation ■ Latch-up free operation ■ High slew rate: 16 V /µs (typ)
Description
The TL071 is a high-speed JFET input single operational amplifier. This JFET input operational amplifier incorporates well matched, high-voltage JFET and bipolar
transistors in a monolithic integrated circuit.
The device features high slew rates, low input bias and offset currents, and low offset voltage temperature coefficient.
