Notes:
1.
VCC/AVCC = Vref = 2.7 to 5.5 V and Topr =
20 to 85°C (N version) / 40 to 85°C (D version), unless otherwise specified.
2.
This applies when one D/A converter is used and the value of the DAi register (i = 0 or 1) for the unused D/A converter is 00h.
The resistor ladder of the A/D converter is not included.
Notes:
1.
VCC = 2.7 to 5.5 V, Topr =
20 to 85°C (N version) / 40 to 85°C (D version), unless otherwise specified.
2.
When the digital filter is disabled.
