Hello together


We want to use the AD7767 for our design. But something in the Data sheet is not clear for me maybe you could help me.


The question is:


The Vref of the ADC is supplied with 5V this means when Vin+ and Vin- are +2.5V we got a digital value of 0x000.

What is when the common mode Volltage of the input is +2.55V (Vin+ 2.55V and Vin- 2.55V). Will be the result also 0x000?


Thanks for you help.
