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 inputpins should be avoided as this significantly reduces the accuracy of the conversion being performed on another analoginput. It is recommended to add a Schottky diode (pin to ground) to standard analog pins which may potentially injectnegative current.Any positive injection current within the limits specified for I INJ(PIN) and ΣI INJ(PIN) in Section 6.3.12 does not affect the ADCaccuracy.3.
