ADE7854A, ADE7858A, ADE7868A, ADE7878A

Hi all,

I'm designing power meter and analyzer. I consider using one of the above mentioned metering ICs.

I was looking at the datasheet for detailed technical specifications, however the datasheet was little confusing.

I need to have an exact list of power measurement parameters for each model (like a comparison matrix) which are accessible through SPI or I2C interfaces.

I've already started to make the comparison matrix, but got stuck. Could anyone help me filling the attached file, where I need to know which of the meters covers the requirements.

In addition I'd like to check if it is possible to use these ICs to measure not one 3-phase network, but three 1-phase networks (like to have three single-phase meters in one IC). 

Thanks in advance,
