An external isolating capacitor allows a non-galvanic connection to special differential or external reference sensor types. Ccc could also be used to lower the overall

capacitance level to a value that is supported by the ZSSC3123 because it limits the maximum capacitance seen by the ZSSC3123 input to CC even if C0 and C1 have

higher values.
