5. Electrical Characteristics

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.
