VREF in AD9695

Category: Hardware
Product Number: AD9695


In our system, we have our analog front end IC board to drive the analog input of the AD9695. We want to use dc-coupled connection so the output stage of our front end circuit needs to provide the same common-mode (CM) voltage as the input CM of the AD9695, which is 1.41V as stated in the datasheet. I notice that your AD9695 provides a input/output called "VREF", and I read through the description but still have some questions.

The main question is that: Can I use this VREF as a reference 1.41V CM voltage for our output stage common-mode feedback circuit? If I understand the following picture correctly, I can control the SPI registers and export a 1.41V voltage reference through this pin? Thanks!
