NOTES
1_{For supply voltages less than ± 22 V, the absolute maximum input voltage is equal}
to the supply voltage.
2_{The OP227 inputs are protected by back-to-back diodes. Current limiting resistors}
are not used in order to achieve low noise. If differential input voltage exceeds ± 0.7
V, the input current should be limited to 25 mA.
3_{␪JA is specified for worst-case mounting conditions, i.e., ␪JA is specified for device}
in socket for CERDIP 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 OP227 features propriety ESD protection circuitry, permanent damage may occur on devices
subjected to high energy electrostatic discharges. Therefor, proper ESD precautions are
recommended to avoid performance degradation or loss of functionality.
