Note 1: Absolute Maximum Ratings are those values beyond which the life
of a device may be impaired.
Note 2: A heat sink may be required to keep the junction temperature
below absolute maximum.
Note 3: The LT1637C and LT1637I are guaranteed functional over the
operating temperature range of – 40°C to 85°C. The LT1637H is guaranteed
functional over the operating temperature range of –40°C to 125°C.
Note 4: The LT1637C is guaranteed to meet specified performance from
0°C to 70°C. The LT1637C 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 LT1637I is guaranteed to meet specified
performance from – 40°C to 85°C. The LT1637H is guaranteed to meet
specified performance from –40°C to 125°C.
Note 5: VS = 5V limits are guaranteed by correlation to VS = 3V and
VS = ±15V or VS = ±22V tests.
Note 6: VS = 3V limits are guaranteed by correlation to VS = 5V and
VS = ±15V or VS = ±22V tests.
Note 7: Guaranteed by correlation to slew rate at VS = ±15V and GBW at
VS = 3V and VS = ±15V tests.
Note 8: This specification implies a typical input offset voltage of 650µV at
VCM = 44V and a maximum input offset voltage of 5.4mV at VCM = 44V.
Note 9: This parameter is not 100% tested.
