* The deviation parameters ∆Vref and ∆Iref are defined as difference between the maximum value and minimum value
obtained over the full operating ambient temperature range that applied.
* The average temperature coefficient of the
reference input voltage, αVref is defined as:
Where: T2-T1 = full temperature change.
αVref can be positive or negative depending on whether Vref Min. or Vref Max occurs at the lower ambient
temperature. Example: ∆Vref=7.2mV and the slope is postive, Vref=1.241V at 25
oC, ΔT=125oC
* The dynamic impedance ZKA is defined as:
* When the device operating with two external resistors, R1 and R2, (refer to Figure 2) the total dynamic impedance of
the circuit is given by:
