Freescale Semiconductor
1. Parasitic capacitance due to package, pin to pin, and pin to package base coupling. (1.8pf)
2. Parasitic capacitance due to the chip bond pad, ESD protection devices and signal routing. (2.04pf)
3. Equivalent resistance for the ESD isolation resistor and the channel select mux. (500 ohms)
4. Sampling capacitor at the sample and hold circuit. Capacitor 4 is normally disconnected from the input and is only connected to it at
sampling time. (1pf)
