Parasitic capacitance due to the chip bond pad, ESD protection devices, and signal routing: 2.04 pF
8 pF noise damping capacitor
Sampling capacitor at the sample and hold circuit. Capacitor C1 is normally disconnected from the input and is only
connected to it at sampling time: C
S1 and S2 switch phases are non-overlapping and operate at the ADC clock frequency.
