Note 1: Absolute Maximum Ratings are those values beyond which the life
of a device may be imparied.
Note 2: The LT1635C is guaranteed to operate over the commercial
temperature range of 0
°C to 70°C. It is designed, characterized and
expected to meet these extended temperature limits, but is not tested at
–40
°C and 85°C. The LT1635I is guaranteed to meet the industrial
temperature range.
Note 3: The LT1635 op amp operates on a 1.2V supply over the full
industrial temperature range with an input common mode voltage of 0V to
0.2V. The minimum supply voltage for the reference to operate properly
over this temperature range is 1.3V.
Note 4: This parameter is not 100% tested. Temperature coefficient is
measured by dividing the change in output voltage by specified
temperature range.
Note 5: Shunt gain defines the operation in floating applications when the
output is connected to the V + terminal and input common mode is
referred to V .
Note 6: If part is stored outside of the specified temperature range, the
output may shift due to hysteresis.
