1. Tested at VDD = +2.7V.
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.
8. Measured as [VFS(VDDMIN) - VFS(VDDMAX)] with external reference.
