Good morning,
I use adum3190 for voltage measurement and I have a problem with the reference voltage level. I did a component simulation and it works very well.
. I've used an external reference voltage and it works very well and also by adding a resistor to the reference voltage level it works too.
on the other hand only with the reference voltage the component saturates before and the reference voltage displays 3.33 v

can you tell me where this problem comes from and how to fix it?
