ADC accuracy
ADC accuracy with fCK_SYS = 20 MHz, fADC=8 MHz, RAIN < 10 kΩ
This assumes that the ADC is calibrated(1)

Refer to ADC accuracy vs. negative injection current on page 73
3.
ADC Accuracy vs. MCO (Main Clock Output): the ADC accuracy can be significantly degraded when
activating the MCO on pin P0.01 while converting an analog channel (especially those which are close to
the MCO pin). To avoid this, when an ADC conversion is launched, it is strongly recommended to disable
the MCO.

ET=Total Unadjusted Error: maximum deviation
between the actual and the ideal transfer curves.
EO=Offset Error: deviation between the first actual
transition and the first ideal one.
EG=Gain Error: deviation between the last ideal
transition and the last actual one.
ED=Differential Linearity Error: maximum deviation
between actual steps and the ideal one.
EL=Integral Linearity Error: maximum deviation
between any actual transition and the end point
correlation line.
