* The deviation parameters V
REF
and I
REF
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, αV
REF
is defined as:
Where: T2-T1 = full temperature change.
αV
REF
can be positive or negative depending on whether V
REF
Min. or V
REF
Max occurs at the lower ambient
temperature. Example: V
REF
=7.2mV and the slope is positive, V
REF
=1.241V at 25°C, T=125°C
* The dynamic impedance Z
KA
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:
