93 / 131 page  R01DS0355EJ0110 Rev.1.10 Page 93 of 131 Sep 29, 2023 RA4M1 Group 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. Note 2. Except for I/O input capacitance (Cin), see section 2.2.4, I/O VOH, VOL, and Other Characteristics. Offset error - ±1.0 ±7.5 LSB High-precision channel ±10.0 LSB Other than above Full-scale error - ±1.5 ±7.5 LSB High-precision channel ±10.0 LSB Other than above Quantization error - ±0.5 - LSB - Absolute accuracy - ±3.0 ±8.0 LSB High-precision channel ±12.0 LSB Other than above DNL differential nonlinearity error - ±1.0 - LSB - INL integral nonlinearity error - ±1.0 ±3.0 LSB - 14-bit mode Resolution --14 Bit - Conversion time*1 (Operation at PCLKC = 8 MHz) Permissible signal source impedance Max. = 5 kΩ 7.50 - - μs High-precision channel ADCSR.ADHSC = 1 ADSSTRn.SST[7:0] = 0Dh 10.88 - - μs Normal-precision channel ADCSR.ADHSC = 1 ADSSTRn.SST[7:0] = 28h Offset error - ±4.0 ±30.0 LSB High-precision channel ±40.0 LSB Other than above Full-scale error - ±6.0 ±30.0 LSB High-precision channel ±40.0 LSB Other than above Quantization error - ±0.5 - LSB - Absolute accuracy - ±12.0 ±32.0 LSB High-precision channel ±48.0 LSB Other than above DNL differential nonlinearity error - ±4.0 - LSB - INL integral nonlinearity error - ±4.0 ±12.0 LSB - Table 2.48 A/D conversion characteristics (7) in low power A/D conversion mode (1 of 2) Conditions: VCC = AVCC0 = 1.6 to 5.5 V (AVCC0 = VCC when VCC < 2.0 V), VREFH0 = 1.6 to 5.5 V Reference voltage range applied to the VREFH0 and VREFL0.
