Description
The TL08x JFET-input operational amplifier family is designed to
offer a wider selection than any previously developed operational
amplifier family. Each of these JFET-input operational amplifiers
incorporates well-matched, high-voltage JFET 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. Offset adjustment and
external compensation options are available within the TL08x
family.
The C-suffix devices are characterized for operation from 0°C to
70°C. The I-suffix devices are characterized for operation from
−40°C to 85°C. The Q-suffix devices are characterized for operation
from −40°C to 125°C. The M-suffix devices are characterized for
operation over the full military temperature range of −55°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.
NOTES: 1. All voltage values, except differential voltages, are
with respect to the midpoint between
VCC+ and VCC−.
2. Differential voltages are at IN+ with respect to IN−.
3. The magnitude of the input voltage must never exceed the
magnitude of the supply voltage
or 15 V, 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.
5. 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.
6. The package thermal impedance is calculated in accordance with
JESD 51-7.
