I'm using the Eval Board of AD7770.
The maximum amplitude I can measure between AIx+ and AIx- is +/- 1.65V (dual supply operation)
According to the AD7770 datasheet, he noted that the maximum amplitude is +/- 2.5V (according to table 11 of the datasheet).

How do I configure my eval board to get such an amplitude?
Thank you in advance and best regards,
Sorry i may have not expressed myself well here. Let me try with pictures.
In my first e-mail i said: see figures 86, that's the way you can get +/-2.5V differential, i.e. if your signal is a true…
