I would like to make sure about AD5291/AD5292 opration voltage.
Data sheet say
Feature: +9V to +33V single-supply operation.
"These devices are capable of operating across a wide voltage range, supporting both dual supply operation at ±10.5 V to ±16.5 V and single supply operation at +21 V to +33 V, while ensuring less than 1% end-to-end resistor tolerance error and offering 20-time programmable (20-TP) memory."
It means AD5292 operate from 9V.
But 1% tolerance needs to supply over 21V ?
What specification will degrade when VDD-VSS is 9V to 21V?
