Electrical characteristics

Figure 30.
Typical connection diagram using the ADC
1.
Refer to Table 44 for the values of CAIN, RAIN, RADC and CADC.
2.
CPARASITIC must be added to CAIN. It represents the capacitance of the PCB (dependent on soldering and
PCB layout quality) plus the pad capacitance (3 pF). A high CPARASITIC value will downgrade conversion
accuracy. To remedy this, fADC should be reduced.
General PCB design guidelines
Power supply decoupling should be performed as shown in Figure 31 or Figure 32,
depending on whether VREF+ is connected to VDDA or not. The 10 nF capacitors should be
ceramic (good quality). They should be placed them as close as possible to the chip.

VREF+ and VREF– inputs are available only on 100-pin packages.
