description
The TL08_ 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 TL08_ family.
Device types with a C suffix are characterized for operation from 0°C to 70°C, those with an I suffix are
characterized for operation from –40°C to 85°C, and those with an M suffix are characterized for operation over
the full military temperature range of –55°C to 125°C.

2. Differential voltages are at the noninverting 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 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.

All characteristics are measured under open-loop conditions with zero common-mode input voltage unless otherwise specified.
Input bias currents of a FET-input operational amplifier are normal junction reverse currents, which are temperature sensitive as shown in
Figure 18. Pulse techniques must be used that will maintain the junction temperatures as close to the ambient temperature as is possible.
