Absolute Maximum Ratings Thermal Information Input Current at I Linearizing Diode Bias Current, I Operating Conditions Temperature Range Thermal Resistance (Typical, Note 2)θJA (oC/W) θJC (oC/W) oC CAUTION: Stresses above those listed in “Absolute Maximum Ratings” may cause permanent damage to the device. This is a stress only rating and operation of the device at these or any other conditions above those indicated in the operational sections of this specification is not implied. NOTES: 1. Short circuit may be applied to ground or to either supply. 2. θJA is measured with the component mounted on an evaluation PC board in free air.
