■ HIGH SLEW RATE : 16V/µs (typ)

DESCRIPTION

The TL084, TL084A and TL084B are high speed J–FET input quad operational a mplifiers 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 offset voltage temperature coefficient.

1. All voltage values, except differential voltage, are with res pect to the zero reference level (ground) of the supply voltages where the zero refer ence

2. The magnitude of the input voltage must never exceed the magnitude of the supply voltage or 15 vol ts, whichever is less.

3. Differential voltages are the non-inverting input terminal w ith respect to the inverting input term inal.

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
