  • RE: INA228-Q1: Negative Current measure

    Resolved
    Hello Corrado, Thank you for using the TI forum. You could use the INA228 with negative VCM if you use isolation, similar to what is done in this reference design: https://www.ti.com/tool/TIDA-00313 Just make sure all the logic levels work with whichever…

  • RE: INA229: Extending Bus voltage range to 400V

    Hello Lukas, You can actually still use the INA229 (SPI) or INA228 (I2C) if you add your own isolation. Here is an example of how his is done with the INA226 at -48V, but the concept can be applied to your setup as well: https://www.ti.com/tool/TIDA-0…
