NOTE 3: When binary output format is used, analog input voltages greater than that applied to REFP convert as all ones (111111111111), while
input voltages less than that applied to REFM convert as all zeros (000000000000). The device is functional with reference down to
1 V. (VREFP VREFM 1); however, the electrical specifications are no longer applicable.
