As for AD4008, can the external reference be powered off during AD4008 standby state?
If there is any concern, please let me know.
I believe this should be no issue on powering off the reference voltage during standby state or the ADC is not converting however just to make sure to have some settling time during power.
Thank you for the answer.
One more question, when standby state, what is the typical current consumption on REF pin?
Typically 300nA on a 5V Vref.
