Description

The TL082, TL082A and TL082B are high speed JFET input dual operational amplifiers incorporating well matched, high voltage JFET and bipolar transistors in a monolithic integrated circuit.

The devices feature high slew rates, low input bias and offset current, 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.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. Destructive dissipation can result from simultaneous shortcircuit on all amplifiers.

5.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

6.Human body model: 100 pF discharged through a 1.5 kΩ resistor between two pins of the device, done for all couples of pin combinations with other pins floating.

7.Machine model: a 200 pF cap is charged to the specified voltage, then discharged directly between two pins of the device with no external series resistor (internal resistor < 5 Ω), done for all couples of pin combinations with other pins floating.

8.Charged device model: all pins plus package are charged together to the specified voltage and then discharged directly to the ground.
