Note 1: Absolute Maximum Ratings are those values beyond which the life
of the device may be impaired.
Note 2: The LT1494C/LT1495C/LT1496C and LT1494I/LT1495I/LT1496I
are guaranteed functional over the operating temperature range of – 40°C
to 85°C. The LT1494H/LT1495H/LT1496H are guaranteed functional over
the operating temperature range of –40°C to 125°C.
Note 3: The LT1494C/LT1495C/LT1496C are guaranteed to meet specified
performance from 0°C to 70°C. The LT1494C/LT1495C/LT1496C are
designed, characterized and expected to meet specified performance from
LT1494H/LT1495H/LT1496H

The LT1494I/LT1495I/LT1496I are guaranteed to meet specified
performance from –40°C to 85°C. The LT1494H/LT1495H/LT1496H are
guaranteed to meet specified performance from –40°C to 125°C.
Note 4: This parameter is not 100% tested.
Note 5: VS = 5V limits are guaranteed by correlation to VS = 3V and
VS = ±15V tests.
Note 6: VS = 3V limits are guaranteed by correlation to VS = 5V and
VS = ±15V tests.
