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: Guaranteed by design, not production tested.

Note 4: Maximum specification is limited by automated test equipment.

Note 5: Defined as the change in positive full scale caused by a ±5% variation in the nominal supply.
