Question about AD5725 reference voltage

Thread Summary

The user inquired about the Vrefp input range for a DAC with AVdd = 5V and Vrefn = 0V, noting that the specified range leaves no margin for power supply and reference errors. The support engineer confirmed that while there is no adjustment margin, this should not affect stability if Vrefp does not need to be adjusted. The user acknowledged that their design does not require adjustable Vrefp but expressed concern about potential instability due to power supply and reference errors.

From the description from datasheet, it is OK as below

AVdd = +5V, AVss=0, DGND =0V, Vrefp = +2.5V, Vrefn=0V

But Vrefp input range given from datasheet is:

The Vrefp input range: min = Vrefn +2.5V , max = AVdd -2.5V

Then min = 0V + 2.5V = max = 5V - 2.5V, there is no margin.

Any more explanation about it?
