    Hi Vigneshwar,

    We setup a DAC38J82 in the configuration that you mentioned above and measured the power consumption. Here are our measurements:

    1. TP18: +3.3V_DAC -> 39.2 mA 

    2. TP26: +1.8V_DAC -> 45.9 mA

    3. TP21: +0.9V_DAC -> 0.131 A

    4. TP28: +0.9V_VDDDIG -> 0.254 A

    Regards, Amy
