1. TJ = –40 to +150 °C, unless otherwise specified and analog input voltage from VAGND to VAREF.

2. AD_CK clock is always half of the ADC module input clock defined via the auxiliary clock divider for the ADC.

3. This is the maximum frequency that the analog portion of the ADC can attain. A sustained conversion at this frequency is

not possible.

4. During the sample time the input capacitance CS can be charged/discharged by the external source. The internal

resistance of the analog source must allow the capacitance to reach its final voltage level within tsample. After the end of the

sample time tsample, changes of the analog input voltage have no effect on the conversion result. Values for the sample

clock tsample depend on programming.

5. This parameter does not include the sample time Tsample, but only the time for determining the digital result.

6. See Figure 10.

1. Typical program and erase times represent the median performance and assume nominal supply values and operation at

25°C. These values are characterized, but not tested.
