102 / 131 page  R01DS0216EJ0120 Rev.1.20 Page 102 of 131 Sep 07, 2020 RX113 Group 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. Note: The characteristics apply when no pin functions other than A/D converter input are used. Absolute accuracy includes quantization errors.
