Note 1. The TYP. value is an average value at T
A
= 25°C. The MAX. value is an average value ±3σ at normal
distribution.
Note 2. These values are the results of characteristic evaluation and are not checked for shipment.
Note 3. A quantization error (±1/2 LSB) is not included.
Note 4. Expressed as a ratio (%FSR) relative to the full-scale value.
Note 5. Be sure to set the LV0 bit in A/D converter mode register 0 (ADM0) to 0 when conversion is done in the
operating voltage range of 2.4 V ≤ V
DD
< 2.7 V.
Note 6. Be sure to set the LV0 bit in A/D converter mode register 0 (ADM0) to 0 when the internal reference voltage is
selected as the target for conversion.
Note 7. Refer to 24.6.3 Internal reference voltage characteristics.
Caution 1. Arrange wiring and insert the capacitor so that no noise appears on the power supply/ground line.
Caution 2. Do not allow any pulses that rapidly change such as digital signals to be input/output to/from the
pins adjacent to the conversion pin during A/D conversion.
Caution 3. Note that the internal reference voltage cannot be used as the reference voltage of the comparator
when the internal reference voltage is selected as the target for A/D conversion.
