Our customer is using ADE7816 evaluation board (EVAL-ADE7816EBZ ).
Then , IRMS value at ICGAIN 0xC00000 is different from expected value (0.5*Irms0).
IRMS at ICGAIN 0x400000 is the same as expected value (1.5*Irms0).
Please let me know your advice if our settings or expected value is correct ?
His register settings is attached.
Attachment describes the register settings of ICGAIN = 0xC00000,0x400000 and 0.
22627LSB ( ICRMS value at attache ICGAIN=0 setting)
0x5863 (22627) at ICGAIN=0x00000
0x848F (33935LSB) at ICGAIN=0x400000
0xDD15(56597LSB) at ICGAIN=0xC00000
Expected value estimation at ICGAIN=0xC00000
Irms =Irms0 *(1+ ICGAIN/2^23) .
ICGAIN is 2's complement and Irms=22627*(1+ (-2^22/2^23) =11313.
