Note:
Table 45.
1. Data guaranteed by design, not tested in production.
Table 46.
1. ADC DC accuracy values are measured after internal calibration.
2. Based on characterization, not tested in production.
Table 47.
1. ADC DC accuracy values are measured after internal calibration.
2. Better performance could be achieved in restricted V
3. Based on characterization, not tested in production.
ADC accuracy vs. negative injection current: Injecting a negative current on any of the
standard (non-robust) analog pins should be avoided as this significantly reduces the
accuracy of the conversion being performed on another analog pin. It is recommended to
add a Schottky diode (pin to ground) to standard analog pins that may potentially inject
negative current.
Any positive injection current within the limits specified for I
