Note 1:
Stresses beyond those listed under Absolute Maximum Ratings
Note 7:
The LT6604C-5 is guaranteed to meet 0°C to 70°C specifi cations may cause permanent damage to the device. Exposure to any Absolute and is designed, characterized and expected to meet the extended Maximum Rating condition for extended periods may affect device temperature limits, but is not tested at –40°C to 85°C. The LT6604I-5 is reliability and lifetime. guaranteed to meet specifi ed performance from –40°C to 85°C.
Note 2:
This is the temperature coeffi cient of the internal feedback
