Hello all,
i am looking for some IC's that should measure current and voltage of symmetrical power source that is galvanic isolated from the CPU. So i will use I2C isolator but for measuring both positive and negative current and voltage and using INA226 i should need two separated isolators. So is possible to use second INA226 with following connections:
GND connected to GND
Vin+ connected to the load side of shunt resistor
Vin- connected to the source side of shunt resistor
Vs connected to the +3.3V
if input stage is fully differential and is powered from the Vs then it should work fine. Am i right?
Many thanks
