188 / 280 page  Document Number: 002-04662 Rev. *F Page 188 of 280 MB91520 Series A/D Converter (1) 12-bit A/D Converter Electrical Characteristics (TA: -40 °C to +125 °C, VCC = AVCC = 5.0 V ± 10 %/VCC = AVCC = 3.3 V ± 0.3 V, VSS = AVSS = 0.0 V) Parameter Symbol Pin Name Value Unit Remarks Min Typ Max Resolution - - - - 12 bit Total error - - - - ±12 LSB Linearity error - - - - ± 4.0 LSB Differential linearity error - - - - ± 1.9 LSB Zero transition voltage VOT AN0 to AN47 AVRL- 11.5LSB - AVRL+ 12.5LSB V 1LSB = (VFST-VOT)/ 4094 Full-scale transition voltage VFST AN0 to AN47 AVRH- 13.5LSB - AVRH+ 10.5LSB V Sampling time tSMP - 0.7 - - µs *1 Compare time tCMP - 0.7 - - µs *1 A/D conversion time tCNV - 1.4 - - µs *1 Analog port input current IAIN AN0 to AN47 -1.0 - +1.0 µA VAVSS ≤ VAIN ≤ VAVCC Analog input voltage VAIN AN0 to AN47 AVRL - AVRH V Reference voltage AVRH AVRH 3.0 - 5.5 V AVRL AVSS/ AVRL - 0.0 - V Power supply current IA AVCC*3 - 0.47 0.63 mA Per unit TA: +105 °C - 0.47 0.7 mA Per unit TA: +125 °C IAH - - 2.5 µA *2 IR AVRH - 1 1.96 mA Per unit IRH - - 1.6 µA *2 Variation between channels - AN0 to AN47 - - 4 LSB *1: Time for each channel. *2: Power supply current (VCC = AVCC = 5.0 V) is specified if A/D converter is not operating and CPU is stopped. *3: The power supply current described only current value on A/D converter. The total AVcc current value must be calculated the power supply current for A/D converter and D/A converter. (Note) Please use the clock of 0.5 MHz-20 MHz for the output clock of A/D converter to guarantee accuracy. |
