  • RE: INA228: INA228 EVB

    Resolved
    Hello Athiq, That may work, depending on your supply. If your ±12V supply is floating, then you would be able to set the -12V as the system GND, making +12V an effective 24V above GND. This will affect the power/VBUS calculations as well though...…

  • RE: INA226: Vbus range

    Hi Chi, Yes this is possible. TI has published a TIDA for this application, which can be found at https://www.ti.com/tool/TIDA-00313 . Regards, Tommy

  • RE: INA238: increase VIL method or pin to pin alternative

    Resolved
    Ah, ya, with 48V VCM, the INA226 will not work for you. I did not realize that you were using an isolator. You may want to look at our similar reference design: https://www.ti.com/tool/TIDA-00313 . I have seen that when using an isolator, capacitors are…

  • RE: INA190: input pin voltage range in bidirectional current measurements

    Resolved
    Alberto, You are correct. While biasing ground to a voltage <0V will provide a small amount of headroom for even lower negative common mode voltages, this will not allow you to get down to -20V. There are a few options for common modes this low: 1…

  • RE: INA260: Is the on-chip shunt isolated from the rest of the device?

    Hello AnBer, Thank you for reaching out on the forum. Could you tell us a little more about your DC DC converter (input, output voltages, and expected current levels, and what general topology are your customer is using). The INA260 shunt is not isolated…
