1.
Based on characterization results, not tested in production.
2.
VREF+ can be internally connected to VDDA and VREF- can be internally connected to VSSA, depending on
the package. Refer to Section 4: Pin description for further details.
3.
VSSA or VREF- must be tied to ground.
4.
Guaranteed by design, not tested in production.
5.
For 1 Msps, maximum Rext is 0.5 k
Ω.

ADC accuracy - limited test conditions(1)(2)
1.
ADC DC accuracy values are measured after internal calibration.
2.
ADC accuracy vs. negative injection current: injecting negative current on any of the standard (non-robust)
analog input pins should be avoided as this significantly reduces the accuracy of the conversion being
performed on another analog input. It is recommended to add a Schottky diode (pin to ground) to standard
analog pins which may potentially inject negative current.
Any positive injection current within the limits specified for IINJ(PIN) and ΣIINJ(PIN) in Section 6.3.11 does not
affect the ADC accuracy.
