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 6.3.13 does not affect the ADC accuracy. 3. Better performance may be achieved in restricted VDDA, frequency and temperature ranges. 4. Data based on characterization results, not tested in production. |
