Problem While reading AC current parameter using Shunt Type with SADC

I am working on Energy Meter Micro controller 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 parameter only .

Please help if any some have any idea about this .

Hardware reference DRM122.
