5. A/D Converter Electrical Characteristics
(AVCC = VCC = +5.0 V
± 5%, AVSS = VSS = 0.0 V, +3.0 V ≤ AVRH – AVRL, TA = –40°C to +70°C)
* : Current applied in CPU stop mode with the A/D converter inactive (VCC = AVCC = AVRH = 5.5 V).
Notes: The error becomes larger as |AVRH–AVRL| becomes smaller.
Use the output impedance of the external circuit for analog input under the following conditions: External
circuit output impedance < Approx. 7 k
If the output impedance the external circuit is too high, the analog voltage sampling time may be insufficient.
(Sampling time = 3.0
s at a machine clock frequency of 16 MHz)
