DESCRIPTION
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.

VCC Supply voltage - note 1)
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-.
±18 V
ViInput Voltage - note 2)
2. The magnitude of the input voltage must never exceed the magnitude of the supply voltage or 15 volts, whichever is less.
±15 V
Vid Differential Input Voltage - note 3)
3. Differential voltages are the non-inverting input terminal with respect to the inverting input terminal.
±30 V
Ptot Power Dissipation 680 mW
Output Short-circuit Duration - note 4)
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
