4. This parameter is characterized before qualification rather than 100% tested.
5. Absolute error includes 1/2 count (~2.5 mV) of inherent quantization error and circuit (differential, integral, and offset) error.
6. Input signals with large slew rates or high frequency noise components cannot be converted accurately. These signals may
