    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

      Hi  ,

      

      

      

      Apologies for the delayed response. 
      

        

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

          

        • This is the difference between the ideal output and the measured output.
          • 

        

        2. 

      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. 

      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).

          

        • When the output is set to Full-scale (0 to -10mA of the x-axis), the expected output should be let’s say Vo = 5V. This is true when the current on the pin is 0mA. However, when sourcing current of 10mA (-10mA), the output drops to around Vo = 4.6V (around -0.4V).
          • 

        • When the output is set to Zero-scale (0 to 10mA of the x-axis), the expected output should be Vo = 0V. This is true when the current on the pin is 0mA. However, when sinking current of 10mA, the output increases to around Vo = 0.6V.

        4. 

      4.  and 5. are also explained in 2. and 3.

        5. 

      

      Regards,
      Flynn
