DESCRIPTION
ORDER CODES
The TL084, TL084A and TL084B are high speed
J–FET input quad operationalamplifiers incorporating
well matched, high voltage J–FET and bipolar transistors in a monolithic integrated circuit.
The devicesfeaturehigh slew rates, low input bias and
offset currents, and low offset voltage temperature
coefficient.

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. Differential voltages are at the non-inverting input terminal with respect to the inverting input terminal.
3. The magnitude of the input voltage must never exceed the magnitude of the supply voltage or 15 volts, whichever is less.
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.
