Electrical characteristics

DocID029968 Rev 3
Figure 29. Typical connection diagram using the ADC
1. Refer to Table 76: ADC characteristics for the values of RAIN and CADC.
2. Cparasitic represents the capacitance of the PCB (dependent on soldering and PCB layout quality) plus the
pad capacitance (refer to Table 71: I/O static characteristics for the value of the pad capacitance). A high
Cparasitic value will downgrade conversion accuracy. To remedy this, fADC should be reduced.
3. Refer to Table 71: I/O static characteristics for the values of Ilkg.
General PCB design guidelines
Power supply decoupling should be performed as shown in Figure 15: Power supply
scheme. The 10 nF capacitor should be ceramic (good quality) and it should be placed as
close as possible to the chip.
