Note 1: Stresses beyond those listed under Absolute Maximum Ratings
may cause permanent damage to the device. Exposure to any Absolute
Maximum Rating condition for extended periods may affect device
reliability and lifetime.
Note 2: Maximum allowable hysteresis depends on desired trip voltages.
See application notes for details.
Note 4: The LTC1998C is guaranteed to meet speci?ed performance from
0°C to 70°C. The LTC1998C is designed, characterized and expected to
meet speci?ed performance from –40°C to 85°C but is not tested or QA
sampled at these temperatures. The LTC1998I is guaranteed to meet
speci?ed performance from –40°C to 85°C.
Note 5: This parameter is not 100% tested.
Note 3: LTC1998C and LTC1998I are guaranteed functional over the
operating temperature range of –40°C to 85°C.
