Hi Team,

Do you have the test data of  current specs for REF_A and REF_B on DAC8728? I can't find it from datasheet. Please share them to me if you have it in hand. Thanks. 

BR,

Eric Jin

    Hi Eric,

    The reference input current can be calculated from the reference voltage divided by the input impedance. As the input impedance is 10 M Ohm (page 5 in datasheet), the current will be sub-nano amperes.

    Hope I have answered your question.
