DESCRIPTION/ORDERING INFORMATION
The TL082 JFET-input operational amplifier incorporates well-matched, high-voltage JFET and bipolar transistors
in a monolithic integrated circuit. The device features high slew rates, low input bias and offset currents, and low
offset-voltage temperature coefficient.
The I-suffix device is characterized for operation from –40°C to 85°C. The Q-suffix device is characterized for
operation from –40°C to 125°C.

Stresses beyond those listed under "absolute maximum ratings" may cause permanent damage to the device. These are stress ratings
only, and functional operation of the device at these or any other conditions beyond those indicated under "recommended operating
conditions" is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
All voltage values, except differential voltages, are with respect to the midpoint between VCC+ and VCC–.
Differential voltages are at IN+ with respect to IN–.
The magnitude of the input voltage must never exceed the magnitude of the supply voltage or 15 V, whichever is less.
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.
Maximum power dissipation is a function of TJ(max), θJA, and TA. The maximum allowable power dissipation at any allowable ambient
temperature is PD = (TJ(max) – TA)/θJA. Operating at the absolute maximum TJ of 150°C can affect reliability.
The package thermal impedance is calculated in accordance with JESD 51-7.
ESD protection level per JEDEC classifications JESD22-A114 (HBM), JESD22-A115 (MM), and JESD22-C101 (CDM).

All characteristics are measured under open-loop conditions with zero common-mode voltage, unless otherwise specified.
Full range for TA is –40°C to 85°C for I-suffix devices and –40°C to 125°C for Q-suffix devices.
Input bias currents of an FET-input operational amplifier are normal junction reverse currents, which are temperature sensitive, as
shown in Figure 14. Pulse techniques must be used that maintain the junction temperature as close to the ambient temperature as
possible.
