31.6 Analog Characteristics

31.6.1 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 AV

REFP = VDD.

Zero-scale error/Full-scale error: Add ±0.05%FSR to the MAX. value when AV

REFP = VDD.

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

REFP = VDD.

Note 4. When AVREFP < VDD, the MAX. values are as follows.

Overall error: Add ±4.0 LSB to the MAX. value when AV

REFP = VDD.

Zero-scale error/Full-scale error: Add ±0.20%FSR to the MAX. value when AV

REFP = VDD.

Integral linearity error/ Differential linearity error: Add ±2.0 LSB to the MAX. value when AV

REFP = VDD.
