Note1. Deviation of reference input voltage, VDEV, is defined as the maximum variation of the reference over the full
temperature range.
The average temperature coefficient of the reference input voltage Ó© VREF is defined as:
Where:
T2 – T1 = full temperature change.
Ó© VREF can be positive or negative depending on whether the slope is positive or negative.
Note2. The dynamic output impedance, RZ, is defined as:
