■ WIDE COMMON-MODE (UP TO V
CC
+
) AND
DIFFERENT IAL VOLTAGE RANGE
■ LOW INPUT BIAS AND OFF SET CURRE NT
■ OUTPUT SHORT-CIRCUIT PROTECTION
■ HIGH INPUT IMPEDANCE J–FET INPUT
STAGE
■ INTERNAL FREQUENCY COMPENSATION

■ HIGH SLEW RATE : 16V/µs (typ)
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.

2. The magnitude of the input voltage must never exceed the magnitude of the supply voltage or 15 vol ts, whichever is less.
3. Differential voltages are the non-inverting input terminal w ith respect to the inverting input term inal.
4. 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
