    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.
