Note 1:
Absolute Maximum Ratings are those values beyond which the life
of a device may be impaired.
Note 2:
Maximum allowable hysteresis depends on desired trip voltages.
See application notes for details.
Note 3:
LTC1998C and LTC1998I are guaranteed functional over the
operating temperature range of –40
°
C to 85
°
C.
Note 4:
The LTC1998C is guaranteed to meet specified performance from
0
°
C to 70
°
C. The LTC1998C is designed, characterized and expected to
meet specified performance from –40
°
C to 85
°
C but is not tested or QA
sampled at these temperatures. The LTC1998I is guaranteed to meet
specified performance from –40
°
C to 85
