STPMC1 update rate/possibble AFE's


Hello everybody. Currently I'm researching different power metering solutions. STPMC1 is a possible contender for my application, but I wasn't able to find some specific information in the datasheet.

These are some things I'm unable to find:
1) How often can the STPMC1 be read? More specifically how often is the data calculated and available to be read out? 
2) Is the STPMC1 only compatible with the STPMxx series AFE's? I'm considering some similar ADC's which could have a higher performance.

Many power metering ICs have a certain accumulation time which corresponds to dynamic range and error, but these devices don't provide that information.

Let me know what I've missed 🙂
