5. A/D Converter Electrical Characteristics
(AVCC = VCC = +2.7 V to +5.5 V, AVSS = VSS = 0.0 V, 2.7 V AVRH – AVRL, TA = –40°C to +85°C)
*1: For VCC = +5.0 V±10% and a 16 MHz machine clock
*2: For VCC = +3.0 V±10% and a 8 MHz machine clock
*3: The current when the A/D converter is not operating or the CPU is in stop mode (for VCC = AVCC = AVRH = +5.0 V).
Notes: The relative error increases as |AVRH – AVRL| decreases.
The output impedance of the external circuit for the analog input should be in the following range.
Output impedance of external circuit < approx. 7 k
If the output impedance of the external circuit is too high, the sampling time for the analog voltage may be
too short. (Sampling time = 3.75
s @4 MHz (This corresponds to 16 MHz internal operation if the multiplier
is 4.))
For an external capacitor to be provided outside the chip, its capacity should desirably be thousands times
larger than that of the capacity in the chip taking in consideration the influence of the capacity distribution
of the external and internal capacitors.
