I posted a simple schematic bypassing the transformers, achieving a 0.5 to 2.5 V DC input range.

Thank you for the answer. And happy new year BTW.

I browsed the manual of the AD and not really understood how the 0.5 to 2.5 V range is resulting for the board in combination with your adaptions. Could you please explain where this range is coming from? And is there a way to change it to 0-2V?

Additionally I have an differental signal coming via the SMA connector. On an oscilloscope I can see the signal moves between 0 and 2V. Is there any way to use this differential signal?
