i´m working in a project with a ade7754 but I do not know why dose calculations are made differently, why do you have high pass filters only in the current channel and why the order of gain and offset are not the same
ADE7754 was one of our earlier products and hence you might see that some of the calculations and internal circuitry might be different than the newer ones. The HPF was only placed in the current channel as the removal of offset error at the current channel was the main concern in terms of accuracy in the power measurement. But for increased perormance levels, HPFs are placed in voltage channels too for most of our newer parts. However in ADE7754, there is a phase correction circuit that compensates for most of the phase shift introduced by the HPF in the current channel alone.
Have you already used one of our newer products and now started using ADE7754? Is there any particular reason for it? What do you mean when you say that the order of gain and offset are different?
