AD7195: ratiometric reference usage

Hello,

 

Sory: one more question!

My system shall measure strain gauge differential signal.

I want to use my system with a ratiometric reference:

I supply the load cells with 8V and I want to use a part of this supply voltage as reference for the AD7195.

In a first approach, i would lik to use a simple voltage divider to make a 5V ref for the AD7195.

By reading the datasheet, I should be carrefull because reference input is not buffered.

 

According to you, what is the best practice to do this way?
