3 Specification applies for TA = 25oC with +12V on Pins 1 and 2; -12V on Pins 6 and 7 for the metal can package and +12V on Pins 1 and2; -12V on Pins 4 and 5 for the dual-in-line package, unless otherwise specified. The parameter guarantees for LH0002C apply over thetemperature range of 0oC to +85oC while parameters for the LH0002 are guaranteed over the temperature range -55oC to +125oC unlessotherwise 2. Absolute Maximum Ratings indicate limits beyond which damage to the device may occur. Operating Ratings indicate conditions forwhich the devices intended to be functional, but do not guarantee specific performance limits. For guaranteed specifications and test conditions,see the Electrical Characteristics. The guaranteed specifications apply only for the test conditions 3.

4 The maximum power dissipation is a function of maximum junction temperature (TJMax), total thermal resistance ( JA), and ambienttemperature (TA) maximum allowed power dissipation at any ambient is PD = (TJMax - TA)/ 4. For operating at elevated temperatures, the device must be derated based on the thermal resistance JA and TJMax. TJ = TA + PD 5.
