Note:
ADC accuracy vs. negative injection current: injecting a negative current on any 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 analog pins which may potentially inject negative currents.
Any positive injection current within the limits specified for IINJ(PIN) and ΣIINJ(PIN) does not
affect the ADC accuracy.

1. Guaranteed by characterization results for BGA packages. The values for LQFP packages might differ.
2. ADC DC accuracy values are measured after internal calibration.
3. ADC clock frequency = 25 MHz, ADC resolution = 16 bits, VDDA=VREF+=3.3 V, BOOST=11 and 16-bit mode.
