ENOB of AD7688  when set 1.0V to VREF.


I have a question from our customer about AD7688 ENOB performance.

In the datasheet page-4, the vref input voltage range is described as 0.5V to VDD+0.3V.

Our customer is going to use 1.0V for vref voltage.

And they needs 14bit ENOB in this condition.

Do you know the ENOB when the vref voltage is 1.0V ?

If you have an ENOB graph, which the vref is extended to 1.0V, please send it to me.

Best regards,
