Note 1. Deviation of reference input voltage, VDEV, is defined as the maximum variatio of the reference over the full temperature range.

The average temperature coefficient of the reference input voltage α VREF is defined as:

Where:

T2-T1 = full temperature change.

α VREF can be positive or negative depending on whether the slope is positive or negative.

Note 2. The dynamic output impedance, RZ, is defined as:
