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)

1.
For optimum ADC performance, keep the minimum VADCIN value > 250mV. Inputs less than 250mV volts may convert to
a digital output code of 0 or cause erroneous conversions.
2.
VREF must be equal to or less than VDDA - 0.3V and must be greater than 2.7V.
3.
Measured in 10-90% range.
4.
LSB = Least Significant Bit.
5.
Guaranteed by characterization.
6.
