95 / 130 page  R01DS0355EJ0100 Rev.1.00 Page 95 of 130 Oct 8, 2019 RA4M1 Group 2. Electrical Characteristics Figure 2.69 Equivalent circuit for analog input Note 1. The internal reference voltage cannot be selected for input channels when AVCC0 < 2.0 V. Note 2. The 14-bit A/D internal reference voltage indicates the voltage when the internal reference voltage is input to the 14-bit A/D converter. Note 3. This is a parameter for ADC14 when the internal reference voltage is used as the high-potential reference voltage. Note 4. This is a parameter for ADC14 when the internal reference voltage is selected for an analog input channel in ADC14. Table 2.49 14-Bit A/D converter channel classification Classification Channel Conditions Remarks High-precision channel AN000 to AN014 AVCC0 = 1.6 to 5.5 V Pins AN000 to AN014 cannot be used as general I/O, IRQ2, IRQ3 inputs, and TS transmission, when the A/D converter is in use Normal-precision channel AN016 to AN025 Internal reference voltage input channel Internal reference voltage AVCC0 = 2.0 to 5.5 V - Temperature sensor input channel Temperature sensor output AVCC0 = 2.0 to 5.5 V - Table 2.50 A/D internal reference voltage characteristics Conditions: VCC = AVCC0 = VREFH0 = 2.0 to 5.5 V*1 Parameter Min Typ Max Unit Test conditions Internal reference voltage input channel*2 1.36 1.43 1.50 V - Frequency*3 1- 2MHz - Sampling time*4 5.0 --μs - Rs Cin Rs Cin Cs ADC MCU Analog input Analog input Sensor ANn ANn |
