1. Refer to Table 63 for the values of RAIN, RADC and CADC.

2. Cparasitic represents the capacitance of the PCB (dependent on soldering and PCB layout quality) plus the

pad capacitance (roughly 7 pF). A high Cparasitic value downgrades conversion accuracy. To remedy this,

fADC should be reduced.
