Figure 40. REFOUT Voltage vs. Temperature (When the AD5737 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.
This second shift is due to the relaxation of stress incurred during soldering.)
