Data Sheet OP27 ABSOLUTE MAXIMUM RATINGS THERMAL RESISTANCETable 5. ParameterRating θJA is specified for the worst-case conditions, that is, θJA is Supply Voltage ±22 V specified for device in socket for TO-99, CERDIP, and PDIP Input Voltage1 ±22 V packages; θJA is specified for device soldered to printed circuit Output Short-Circuit Duration Indefinite board for SOIC package. Differential Input Voltage2 ±0.7 V Absolute maximum ratings apply to both dice and packaged Differential Input Current2 ±25 mA parts, unless otherwise noted.

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. Stresses at or above those listed under Absolute Maximum Ratings may cause permanent damage to the product. This is a stress rating only; functional operation of the product at these or any other conditions above those indicated in the operational section of this specification is not implied. Operation beyond the maximum operating conditions for extended periods may affect product reliability. Rev. H | Page 7 of 21
