BLOCK DIAGRAM
* 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 30°C, minimum VREF =2.492V at 0°C, VREF =2.495V at 25°C, ΔT=70°C
αV_REF | = [4mV / 2495mV] * 10⁶ / 70°C ≈ 23ppm/°C
Because minimum VREF occurs at the lower temperature, the coefficient is positive.
* The dynamic impedance ZKA is defined as:
| Z_KA | = ΔV_KA / ΔI_KA
* 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:
| Z_KA | = Δv / Δi | ≈ Z_KA | * ( 1 + R1 / R2)
