104 / 139 page  R01DS0307EU0100 Rev.1.00 Page 104 of 139 Mar 7, 2017 S3A3 2. Electrical Characteristics Note: The characteristics apply when no pin functions other than 14-bit A/D converter input are used. Absolute accuracy does not include 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. The number of sampling states is indicated for the test conditions.
