* CKA greater than 100nF is needed for stability.
Note 1:
The deviation parameter ΔVref is defined as the differences
between the maximum and minimum values obtained over the
full operating ambient temperature range that applies.
Example : ΔVref = 5.0mV and slope is positive,
Vref at 25=1.245V, ΔTa=110
0.005×106

Note 2: The dynamic impedance Zka is defined as:
ΔVKA
|Zka| = ΔIk
When the device is programmed with two external
resistors, R1 and R2, (refer to Figure 2) the total
dynamic impedance of the circuit is defined as:
R1
|Zka'| = |Zka| (1+ R2 )
The average temperature coefficient of the Reference
input voltage, ΔVref , is defined as:
ΔVref
(
) × 106
ppm
αVref ( ) =
Vref at 25
ΔTa
= ΔVref × 106
ΔTa(Vref at 25)
αVref can be positive or negative depending on whether
Vref Min. or Vref Max. occurs at the lower ambient temperature.
