2. Relative accuracy is the deviation of the analog value at any code from its theoretical value after the full-scale

range and offset have been calibrated.

3. Offset nulled.

4. Achievable with standard timing (see Figure 25 on page 14).

5. Sample tested at 0.1% AQL.

6. External load should not change during conversion for specified accuracy.

7. Guaranteed by design; not subject to production testing.
