i want to measurement 3phase/3wire voltage

to use msp430afe mcu or another

is it possible?

input : R, S, T

measurement voltage : R-S, R-T, S-T

kim kwangho92337,

Were you able to get it to work. I am looking to build a similar circuit to measure 3 phase voltage on 3 wire. Did you not face any issue with common mode voltage on the differential inputs?

Why don't you check TI 3-phase meter reference design?
