What is the input voltage range for the AD586LRZ that would allow it to meet its published specifications ? The datasheet only indicates test condition of Vin=15V.
I still need to verify the input voltage range of this part to the product owner. Meanwhile, what drives you to use this reference voltage? This part is kinda old (20 years ago). One of our expert recommend the ADR435 for 5 V reference voltage(https://ez.analog.com/message/35334#35334). You may also want to consider this part while I am still checking on the input voltage range for the AD586..
