1. Guaranteed by design.

2. Difference between two consecutive codes - 1 LSB.

3. Difference between measured value at Code i and the value at Code i on a line drawn between Code 0 and last Code 4095.

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

5. 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 (VREF+ – 0.2) V when buffer is ON.
