PARAMETER DEFINITIONS
TEMPERATURE COEFFICIENT
Temperature coefficient is defined as the change in output
voltage with respect to operating temperature changes and is
normalized by the output voltage at 25°C. This parameter is
expressed in ppm/°C and is determined by the following
equation:

THERMAL HYSTERESIS
Thermal hysteresis is defined as the change in output voltage
after the device is cycled through temperatures ranging from
+25°C to −40°C, then to +85°C, and back to +25°C. The
following equation expresses a typical value from a sample of
parts put through such a cycle:
