2. This value is indicated as a ratio (%FSR) to the full-scale value.
3. Refer to 30.6.2 Temperature sensor/internal reference voltage characteristics.
4. When reference voltage (−) = V
SS, the MAX. values are as follows.
Zero-scale error: Add ±0.35%FSR to the MAX. value when reference voltage (−) = AV
REFM.
Integral linearity error: Add ±0.5 LSB to the MAX. value when reference voltage (−) = AV
REFM.
Differential linearity error: Add ±0.2 LSB to the MAX. value when reference voltage (−) = AVREFM.
