Voltage Reference for COM input in AD7689

Hi!

I'm planning to use the AD7689 in bipolar range, so I will need to apply Vref/2 in the COM port.

 

Is there a particular way you recommend to achieve this?

I noticed that in the EVAL-AD76MUXEDZ schematic a voltage divider from the REF pin is used.

 

Thanks!

Andres
