1. Refer to Table 66 for the values of R
AIN
.
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 will downgrade conversion accuracy. To remedy
this, f
ADC
should be reduced.
General PCB design guidelines
Power supply decoupling should be performed as shown in Figure 11. The 10 nF capacitor
should be ceramic (good quality) and it should be placed as close as possible to the chip.
