LT1636
ELECTRICAL CHARACTERISTICS
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. The θJA specified for the DD package is with
minimal PCB heat spreading metal. A significant reduction in θJA can be
obtained with expanded PCB metal area on all layers of a board.
Note 3: The LT1636C and LT1636I are guaranteed functional over the
operating temperature range of – 40°C to 85°C. The LT1636H is
guaranteed functional over the operating temperature range of –40°C to
125°C.
Note 4: The LT1636C is guaranteed to meet specified performance from
0°C to 70°C. The LT1636C 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 LT1636I is guaranteed to meet
specified performance from – 40°C to 85°C. The LT1636H 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 600µV at
VCM = 44V and a maximum input offset voltage of 3mV at VCM = 44V.
Note 9: This parameter is not 100% tested.
