General Description
The JFET-input operational amplifier family is designed to offer a
wider selection than any previously developed operational
amplifier family. Eac h of these JFET-i nput operatio nal 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.

Notes: 3. ALL voltage values, except differential voltages, are with respect to the midpoint between V
4. Differential voltage are at the non-inverting input terminal with respect to the inverting input terminal.
5. The magnitude of the input voltage must never exceed the magnitude of the supply voltage or 15V, whichever is less.
6. The output may be shorted to ground or either supply. Temperature and/or supply voltage must be limited to ensure that the dissipation rating is
not exceeded.
7. Maximum power dissipati on is a function of T
temperature is P
=(TJ(max)-TA)/ θJA . Operating at the absolute maximum TJ of 150℃ can affect reliability
