This second shift is due to the relaxation of stress incurred during soldering.)
Figure 63. REFOUT vs. Temperature (When the AD5755-1 is soldered onto a
PCB, the reference shifts due to thermal shock on the package. The average
output voltage shift is −4 mV. Measurement of these parts after seven days
shows that the outputs typically shift back 2 mV toward their initial values.
