DESCRIPTION
The TL081, TL081A and TL081B are high speed
J–FET input single operational amplifiers incorporating well matched, high voltage J–FET 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.

All voltage values, except differential voltage, are with respect to the zero reference level (ground) of the supply voltages where the zero reference
level is the midpoint between VCC + and VCC -.
The magnitude of the input voltage must never exceed the magnitude of the supply voltage or 15 volts, whichever is less.
Differential voltages are thenon-inverting input terminal with respect to the inverting input terminal.
The output may be shorted to ground or to either supply. Temperature and/or supply voltages must be limited to ensure that the dissipation rating
is not exceeded
