TL081
TL081
General purpose JFET single operational amplifiers
Features
Wide common-mode (up to VCC+) and
differential voltage range
Low input bias and offset current
Output short-circuit protection
High input impedance JFET input stage
Internal frequency compensation
Latch-up free operation
High slew rate: 16 V/µs (typ)
Description
The TL081, TL081A and TL081B are high-speed
JFET input single operational amplifiers
incorporating well matched, high-voltage JFET
and bipolar transistors in a monolithic integrated
circuit.
The devices feature high slew rates, low input
bias and offset currents, and low offset voltage
temperature coefficient.
