I suggest to read the ADC datasheet regarding suggested options for DC input signals. I mentioned a true differential driver, which is the best option in terms of supressing common mode interferences and also achieves best ADC linearity.

A single ended configuration would e.g. remove R1, C1 and T2, connect left side of R5 to VNCT_A and left side of R4 to input jack. The input voltage range is 0.5 to 2.5 then.
