1. Guaranteed by design, not tested in production.

2. Connected between DAC_OUT and VSSA.

3. Difference between two consecutive codes - 1 LSB.

4. Difference between measured value at Code i and the value at Code i on a line drawn between Code 0 and last Code

4095.

5. Difference between the value measured at Code (0x800) and the ideal value = VDDA/2.

6. Difference between the value measured at Code (0x001) and the ideal value.

7. Difference between ideal slope of the transfer function and measured slope computed from code 0x000 and 0xFFF when

buffer is off, and from code giving 0.2 V and (VDDA – 0.2) V when buffer is on.

8. In buffered mode, the output can overshoot above the final value for low input code (starting from min value).
