Hi everyone,

I am designing circuit to measure the inline currents of each BLDC motor phase. Because the ADC (AD7380-4) has fully differential analog inputs I came up with 2 different solutions of how to connect the CSA (MAX40056U) to the ADC:

- use the pseudo-differential signal or

- convert single-ended signal to fully differential one

Below I attached two schematics. I would like to ask you to have a look and say if they are correct and which way is more proper. Thank you in advance.
