ORDER CODE
DESCRIPTION
Part Number

The TL084, TL084A and TL084B are high speed
J–FET input quad 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 offsetvoltage temperature coefficient.

All voltage values, except differential voltage, are with respectto 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 the non-inverting input terminal with respect to the inverting input terminal.
The output may be shorted to ground orto either supply. Temperature and/or supply voltages must be limited to ensure that the dissipation rating
is not exceeded
