PARAMETER DEFINITIONS

TEMPERATURE COEFFICIENT

This is the change of output voltage with respect to the

operating temperature changes, normalized by the output

voltage at 25°C. This parameter is expressed in parts per

million/degrees Celsius (ppm/°C) and can be determined with

the following equation:

THERMAL HYSTERESIS

Thermal hysteresis is the change of output voltage after the

device is cycled through the temperature from 25°C to 0°C to

85°C and back to 25°C.
