6. ThERMal hYSTERISIS

A change in output voltage as a result of a temperature change. When references experience a temperature change

and return to the initial temperature, they do not always have the same initial voltage. Thermal hysterisis is difficult to

correct and is a major error source in systems that experience temperature changes greater than 25°C. Reference

vendors are starting to include this important specification in their datasheets.
