7 / 12 page Data Sheet ADR512 Rev. A | Page 7 of 12 PARAMETER DEFINITIONS TEMPERATURE COEFFICIENT This is the change of output voltage with respect to operating temperature changes, normalized by the output voltage at 25°C. This parameter is expressed in ppm/°C and can be determined with the following equation: ( ) ( ) ( ) ( ) 6 1 2 1 2 10 25 × − × ° − = ° T T C V T V T V C ppm TCV O O O O (1) where: VO(25°C) = VO at 25°C VO(T1) = VO at Temperature 1 VO(T2) = VO at Temperature 2 THERMAL HYSTERESIS Thermal hysteresis is defined as the change of output voltage after the device is cycled through the temperature from +25°C to −40°C to +85°C and back to +25°C. This is a typical value from a sample of parts put through such a cycle.
