ADE7753 for DC energy tracking

Hi.

 

We are looking at the possibility to use an ADE7753 to measure DC power. According to AN-639, page 8, once can expect 1% error for 100:1 range in general for the family. Can anyone confirm this? Also, if our upper measurement is at 200A, what can we expect below 2A, as this will be an energy tracking appl, so due to integration we need fairly good accuracy at small currents.

 

Thanks beforehand.
