2. INL and DNL specifications for 12-bit mode do not include the first or last four ADC codes.
3. The maximum code in 12-bit mode is 0xFFFC. The Full Scale Error is referenced from the maximum code.
4. Performance in 8-bit mode is similar to 10-bit mode.

sensor, varies with the voltage of the previously sampled channel and can be up to 6 µs if the previously
sampled channel voltage was greater than 3 V. To minimize the temperature sensor settling time, the ADC
mux can be momentarily set to ground before being set to the temperature sensor output. This ensures that
the temperature sensor output will settle in 3 µs or less.
