The TL084, TL084A and TL084B are high speed
J–FET input quad operational amplifiers incorpo-
rating well matched, high voltage J–FET and bipo-
lar transistors in a monolithic integrated circuit.
The devices feature high slew rates, low input bias
and offset currents, and low offset voltage temper-
ature 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 V
CC +
and V
CC -
.
The magnitude of the input voltage must never exceed the magnitude of the supply voltage or 15 volts, whichever is less.
Differential voltages are the non-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
