57 / 67 page MB90860E Series 57 5. A/D Converter (TA = −40 °C to +105 °C, 3.0 V ≤ AVRH − AVRL, VCC = AVCC = 5.0 V ± 10%, fCP ≤ 24 MHz, VSS = AVSS = 0 V) * : IF A/D convertor is not operating, a current when CPU is stopped is applicable (VCC = AVCC = AVRH = 5.0 V) . Note : The accuracy gets worse as AVRH − AVRL becomes smaller.
