Figure 21. Input equivalent circuit (extended channels)
A second aspect involving the capacitance network shall be considered. Assuming the three capacitances CF, CP1 and CP2 are
initially charged at the source voltage VA (refer to the equivalent circuit in Figure 20): A charge sharing phenomenon is installed
when the sampling phase is started (A/D switch close).
Figure 22. Transient behavior during sampling phase
In particular two different transient periods can be distinguished:
RF
CF
RS
RL
RSW1
CP3
CS
VDD
