8.3.2 Low Temperature Drift

The REF20xx is designed for minimal drift error, which is defined as the change in output voltage over temperature. Use Equation 4 to calculate the drift using the box method:

Equation 4. D r i f t = V R E F M A X - V R E F M I N V R E F × T e m p e r a t u r e   R a n g e × 10 6 p p m
