Parasitics
For the correct calculation of the external capacitors the parasitic capacitances of the pins and the
switches (C
20
, C
21
, C
22
) have to be taken into account.

parasitics of the switching network
With the given parasitics the actual C
v
can be calculated:
Note
: Please keep in mind also to include the Pad parasitics of the circuit board.
