TL082
GENERAL PURPOSE DUAL
J-FET OPERATIONAL
AMPLIFIER
DESCRIPTION
The UTC TL082 is a high speed J-FET input dual
operational amplifier. It incorporates well matched,
high voltage J-FET and bipolar transistors in a
monolithic integrated circuit.
The device features high slew rates, low input bias
and offset current, and low offset voltage temperature
coefficient.
FEATURES

NOTES: 1. 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+.
2. The magnitude of the input voltage must never exceed the magnitude of the supply voltage
or 15 volts, whichever is less.
3. Differential voltages are at the non-inverting input terminal with respect to the inverting input
terminal.
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 is not exceeded.
