Notes 1. TYP. Value is the average value at T
A = 25°C. MAX. value is the average value ±3σ at normal distribution.
2. These values are the results of characteristic evaluation and are not checked for shipment.
3. Excludes quantization error (±1/2 LSB).
4. This value is indicated as a ratio (%FSR) to the full-scale value.
5. Set the LV0 bit in the 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.
6. Set the LV0 bit in the A/D converter mode register 0 (ADM0) to 0 when the internal reference voltage is
selected as the target for conversion.
7. Refer to 24.6.3 Internal reference voltage characteristics.
Cautions 1. Arrange wiring and insert the capacitor so that no noise appears on the power supply/ground
line.
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.
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.
