1. Refer to Table 63 for the values of R_AIN, R_ADC and C_ADC.
2. C_parasitic represents the capacitance of the PCB (dependent on soldering and PCB layout quality) plus the
pad capacitance (roughly 7 pF). A high C_parasitic value downgrades conversion accuracy. To remedy this,
f_ADC should be reduced.
