How to design 1-phase shunt electricity meters using standalone metrology ADCs

As processing requirements for electricity meters gradually increase, it becomes increasingly difficult to find one device that meets both the processing requirements for adding advanced metrology features to smart meters while also accurately sensing metrology parameters, such as RMS voltage, RMS current and active power.  To deal with this design challenge, one option is to use a separate metrology microcontroller and a standalone ADC.
