further explanations.
This represents an equivalent switched capacitance. This capacitance is not switched to the reference voltage
at once. Instead of this smaller capacitances are successively switched to the reference voltage. Alternatively,
the redistributed charge could be specified.
The switched capacitance at the analog voltage input must be charged within the sampling time. Alternatively,
the redistributed charge could be specified.
