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. 3JA is specified for worst case mounting conditions, i.e., JA is specified for device in socket for TO, CerDIP, P-DIP, and LCC packages; JA is specified for device soldered to printed circuit board for SO package. 4Absolute maximum ratings apply to both DICE and packaged parts, unless otherwise noted. 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 OP37 features proprietary ESD protection circuitry, permanent damage may occur on devices subjected to high-energy electrostatic discharges. Therefore, proper ESD precautions ESD SENSITIVE DEVICE are recommended to avoid performance degradation or loss of functionality. –2– REV.
