About single ended input to ADE7878

Hi,

I am designing energy meter by using ADE7878. ADE7878 works well in my previous design with differential inputs to IAP, IAN,IBP and IBN, and ICP and ICN.

But in my new design, I have to use single ended input to ADE7878.

My questions are:

1. Can the singled ended input from CT  be allowed to connect to ADE7878 or similar IC?

2. if so, May I have its reference design? Is the accuracy affected?

thanks,

Regards,
