ELECTRICAL C
realized by preconditioning the IC with a 100-200 hour, 125
°
C burn in.
Long term stability will also be affected by differential stresses between the
IC and the board material created during board assembly. Temperature
cycling and baking of completed boards is often used to reduce these
stresses in critical applications.
Note 7:
Hysteresis in output voltage is created by package stress that
differs depending on whether the IC was previously at a higher or lower

temperature. Output voltage is always measured at 25
°
C, but the IC is
cycled to 50
°
C or 0
°
C before successive measurements. Hysteresis is
roughly proportional to the square of temperature change. Hysteresis is
not normally a problem for operational temperature excursions, but can be
significant in critical narrow temperature range applications where the
instrument might be stored at high or low temperatures.
