Note: The characteristics apply when no pin functions other than A/D converter input are used. Absolute accuracy includes
quantization errors. Offset error, full-scale error, DNL differential nonlinearity error, and INL integral nonlinearity error do not
include quantization errors.
Note 1. The conversion time is the sum of the sampling time and the comparison time. As the test conditions, the number of sampling
states is indicated.
Note 2. The value in parentheses indicates the sampling time.

Note 1. The internal reference voltage cannot be selected for input channels when AVCC0 < 2.0 V.
Note 2. The A/D internal reference voltage indicates the voltage when the internal reference voltage is input to the A/D converter.
