TERMINOLOGY
Temperature Coefficient
The change in output voltage with respect to operating temperature
changes. It is normalized by an output voltage of 25°C. This
parameter is expressed in ppm/°C and is determined by the
following equation:

Thermal Hysteresis
The change in output voltage after the device is cycled through
temperatures ranging from +25°C to −40°C, then to +125°C, and
back to +25°C. This is common in precision reference and is
caused by thermal-mechanical package stress. Changes in envi-
ronmental storage temperature, board mounting temperature, and
the operating temperature are some of the factors that can
contribute to thermal hysteresis. The following equation
expresses a typical value from a sample of parts put through
such a cycle:
