Electrical characteristics

EG = Gain error: The deviation between the last ideal transition and the last actual transi-

tion.

ED = Differential linearity error: The maximum deviation between the actual step and the

ideal value.

EL = Integral linearity error: The maximum deviation between any actual conversion and

the associated line of the endpoint.

1. See Table 42 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 7pF) . A high Cparasitic value will

downgrade conversion accuracy. To remedy this, fADC should be reduced.

PCB design recommendations

The power supply must be connected as shown below. The 10nFcapacitor in the figure

must be a ceramic capacitor (good quality) , and they should be as close as possible to

the MCU chip.
