ADR5040/ADR5041/ADR5043/ADR5044/ADR5045 Data Sheet Rev. B | Page 10 of 16 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: ( ) ( ) ( ) ( ) 610C25C ppm ×−×° −= ° 12UTO 1OUT2OUT OUT TTV TVTVTCV (1) where: VOUT(25°C) = VOUT at 25°C. VOUT(T1) = VOUT at Temperature 1. VOUT(T2) = VOUT at Temperature 2. 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: ( ) [ ] ( ) ( ) 10C25 C25ppm C25 −°= −°= OUT TCOUTOUT HYSOUT TCOUTOUTHYSOUT V VVV VVV (2) where: VOUT(25°C) = VOUT at 25°C. VOUT_TC = VOUT at 25°C after a temperature cycle from +25°C to −40°C, then to +125°C, and back to +25°C.
