Questions about Figure 27 in the datasheet

Hello,
This is Kwonjoon Lee from South Korea.

I would like to ask about Figure 27 of the datasheet of AD5602.

(Detailed Questions about Figure 27)

1. I would like to ask if the ΔVo(V) in the y-axis means (actual output voltage - intended output voltage).

2. I would like to ask if a positive value of the I(mA) in the x-axis means the current flowing into the DAC output (from the Load).

3. I would like to ask if a negative value of the I(mA) in the x-axis means the current flowing into the Load (from the DAC output).

4. I would like to ask if "DAC LOADED WITH ZERO-SCALE CODE" means the graph in the right half plane.

5. I would like to ask if "DAC LOADED WITH FULL-SCALE CODE" means the graph in the left half plane.

Best regards,
Kwonjoon Lee
