Part Number: INA219

Hi,Team

We would like to design current sense circuit with INA219.

In circuit, input is 12V, max current is 10A

Which part do you recommend for current sense resistor?

thanks

    Perry,

    Thanks for the question and using the E2E forum.

    There are a lot of considerations when selecting a shunt resistor (tolerance, accuracy, power, etc.). I suggest you start with this video we've put together as a guide for exactly this question.

    Please let us know if you have any questions after watching the video.
