Note 1: Relative accuracy is the deviation of the analog value at any code from its theoretical value after offset and gain errors have
been removed.
Note 2: Offset nulled.
Note 3: Maximum specification is limited by automated test equipment.
Note 4: Defined as the change in positive full scale caused by a ±5% variation in the nominal supply.
Note 5: To ensure best performance, finish reading the data and wait t_BR before starting a new acquisition.
