    Thread Summary
    
                The user is evaluating the ADE9178EVKIT and seeking clarification on how the AD converter output code from the ADE9113 is converted to the register value. The final answer indicates that the ADC output is a 24-bit signed (two's complement) value, and the user should refer to the ADC Transfer Function section in the upcoming Rev A datasheet for more details. The user replaced the 500uΩ shunt resistor with a 100uΩ resistor for measurements.

    I am considering configuring a DC power meter using the ADE9113 and ADE9178,
    

    and I have started my evaluation using the evaluation board ADE9178EVKIT#
    

    Since the calculated value and the measured value of the AD converter output code of ADE9113 are almost the same,
    

    I believe that the current value is being measured accurately.
    

    This ADC outputs code are stored in register.
    

    I don't understand how it gets converted.
    

    Please tell me how it is converted from the AD converter output code to this value.
