Thermal Hysteresis

Thermal hysteresis for the REF50xx is defined as the change in output voltage after operating the device at 25°C, cycling the device through the specified temperature range, and returning to 25°C. Thermal hysteresis can be expressed as Equation 3:

Equation 3. REF5010 REF5020 REF5025 REF5030 REF5040 REF5045 REF5050 q_hysteresis_bos410.gif

where

  • VHYST = thermal hysteresis (in units of ppm).
  • VNOM = the specified output voltage.
  • VPRE = output voltage measured at 25°C pretemperature cycling.
  • VPOST = output voltage measured after the device has been cycled from 25°C through the specified temperature range of –40°C to 125°C and returned to 25°C.
