A/D Converter Electrical Characteristics
(3.0 V
≤ AVR AVSS, VCC = AVCC = 5.0 V±10%, VSS = AVSS = 0.0 V, TA = 40 °C to +85 °C)
* : The current when the A/D converter is not operating or the CPU is in stop mode (for VCC = AVCC = AVR = 5.0 V)
Note : The error increases proportionally as |AVR - AVSS| decreases.
