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.
