These values define
the range over which
the ADC performs
within spec; exceeding
these values does not
cause damage or insta-
bility; see DC Charac-
teristics for absolute
pin voltage limits.
Notes:
1. Analog source impedance affects the ADC offset voltage (because of pin leakage) and input settling time.
2. Devices are factory calibrated at VDD = 3.3V and TA = +30°C, so the ADC is maximally accurate under these
conditions.
3. LSBs are defined assuming 10-bit resolution.
4. This is the maximum recommended resistance seen by the ADC input pin.
5. The input impedance is inversely proportional to the system clock frequency.
