MSP430F67641: We need a power calculation chip for the meter to detect the power consumption of the 220V AC input port.

We need a power calculation chip for the meter to detect the power consumption of the 220V AC input port. I found the TIDA-01088 solution, please help to determine if it can be realized?

In the integrated solution, limited by the common-mode voltage range, the maximum is 85V. Can you monitor 220V? If not, are there any other suitable solutions?

Thanks.

    Yes, if your current sensors are shunts, this solution will work. If you can use current transformers (CTs), check out the EVM430-F6779 and consider using the Energy Measurement Design Center (EMDC).

    What does "integrated solution" mean? With the TIDA-01088 design, you can measure 230VAC. See Section 3.1.1.1 Voltage Analog Front-End in the user's guide.
