2. ELECTRICAL SPECIFICATIONS (A, D: TA = −40 to +85°C)
Notes 1. Excludes quantization error (±1/2 LSB).
2. This value is indicated as a ratio (%FSR) to the full-scale value.
<R>
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.
