The

l denotes the speciﬁcations which apply over the full operating

temperature range, otherwise speciﬁcations are at TA = 25°C. VGND = 0V, unless otherwise noted.

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 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°C.

Note 5: This parameter is not 100% tested.
