ADS1299EEGFE-PDK: ADS1299 "Analog input" isolation

Part Number: ADS1299EEGFE-PDK
Other Parts Discussed in Thread: ADS1299

Tool/software:

I recently attended a seminar on the basics of galvanic isolation.

I measured the DC voltage at the input terminal of an ADS1299 evaluation board.

The DC voltage was 0V, but is there any isolation, such as C-cut, inside the IC?
