* 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 the slope is positive or negative.
Example: Maximum Vref=2.496V at 30oC, minimum Vref=2.492V at 0oC, Vref=2.495V at 25oC, ΔT=70 oC
Because minimum Vref occurs at the lower temperature, the coefficient is possitive
* 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:
