Analog Characteristics

2.6.1

A/D converter characteristics

Note 1.

Excludes quantization error (±1/2 LSB).

Note 2.

This value is indicated as a ratio (%FSR) to the full-scale value.

Note 3.

When AVREFP < VDD, the MAX. values are as follows.

Overall error:

Add ±1.0 LSB to the MAX. value when AVREFP = VDD.

Zero-scale error/Full-scale error:

Add ±0.05%FSR to the MAX. value when AVREFP = VDD.

Integral linearity error/ Differential linearity error: Add ±0.5 LSB to the MAX. value when AVREFP = VDD.

Note 4.

Values when the conversion time is set to 57

μs (min.) and 95 μs (max.).

Note 5.

Refer to 2.6.2 Temperature sensor characteristics/internal reference voltage characteristic.
