Hi team.

I want to use two INA226 with different address to sense the same shunt resistor. Is that OK?

    Hi Naizeng, 

    This should theoretically work, as long as you use the proper kelvin connections in layout to reduce Ib for both parts. Please let me know if you have any questions, or run into any errors, I would be glad to support. 

    Best,
