Common mode voltage

Hi,

 

The AD7621 datasheet indicate that the differential input range is +/-2,048Vp with Vref = 2,048V (4,096 Vpp input span).

We suppose that the common mode voltage for Vin+ and Vin- is VREFBUFIN (1,2V with Vref = 2,048V). Is it right?

Also, do you confirm that the value of the common mode voltage for Vin+ and Vin- when Vref = 2,5V is 1,3V ?

 

Thank in advance for your answer,

Best regards,
