Lead Temperature Range (Soldering 60 sec) . 300∞C 2The OP470’s inputs are protected by back-to-back diodes. Current limiting Junction Temperature (Tj) . –65∞C to +150∞C resistors are not used in order to achieve low noise performance. If differential Operating Temperature Range voltage exceeds ± 1.0 V, the input current should be limited to ± 25 mA.

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 WARNING! the OP470 features proprietary ESD protection circuitry, permanent damage may occur on devices subjected to high energy electrostatic discharges. Therefore, proper ESD precautions are ESD SENSITIVE DEVICE recommended to avoid performance degradation or loss of functionality. REV.
