NOTES
1_{Absolute maximum ratings apply to both DICE and packaged parts, unless}
otherwise noted.
2_{For supply voltages less than ± 20 V, the absolute maximum input voltage is equal}
to the supply voltage.
3_{θJA is specified for worst case mounting conditions, i.e., θJA is specified for device in}
socket for cerdip and P-DIP, packages; θJA is specified for device soldered to printed
circuit board for SO package.

CAUTION
ESD (electrostatic discharge) sensitive device. Electrostatic charges as high as 4000 V readily
accumulate on the human body and test equipment and can discharge without detection.
Although the OP297 features proprietary ESD protection circuitry, permanent damage may
occur on devices subjected to high energy electrostatic discharges. Therefore, proper ESD
precautions are recommended to avoid performance degradation or loss of functionality.
