S
1. Analog source impedance affects the ADC offset voltage (because of pin leakage) and input settling time.
2. Devices are factory calibrated at V DD = 3.3 V and T A = +30 °C, so the ADC is maximally accurate under these
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.
