Problem While reading AC current  using Shunt Type with SADC

I am working on Energy Meter Micrcontroller IC  #MKM34Z256VLQ7 

Now I am stuck while reading  current  parameter from  SADC 24 bit   and  getting SADC count with more variation and not seen any repetition while testing with 0 to 500mv

I have tested  rang of  0 to 500mV voltage by applying  DC volt and its working well with this with no variation  .

But variation occur with the AC voltage given to circuit .

Please help if some have any idea about this .

Hardware reference DRM122.
