1. ADC DC accuracy values are measured after internal calibration.

2. ADC accuracy vs. negative Injection Current: Injecting 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 current.

Any positive

3. Better performance may be achieved in restricted VDDA, frequency and temperature ranges.

4. Guaranteed by characterization results.

5. Value measured with a -0.5 dB full scale 50 kHz sine wave input signal.
