Description
The TL084, TL084A and TL084B are high-speed
JFET input quad operational amplifiers
incorporating well matched, high voltage JFET
and bipolar transistors in a monolithic integrated
circuit.

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 the non-inverting input terminal with respect to the inverting input terminal.
4. Short-circuits can cause excessive heating and destructive dissipation.
5. Rth are typical values.
6. 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.
7. Human body model: 100pF discharged through a 1.5kΩ resistor between two pins of the device, done for all couples of pin
combinations with other pins floating.
8. Machine model: a 200pF cap is charged to the specified voltage, then discharged directly between two pins of the device
with no external series resistor (internal resistor < 5Ω), done for all couples of pin combinations with other pins floating.
9. Charged device model: all pins plus package are charged together to the specified voltage and then discharged directly to
the ground.
