| Jun 9, 2017 at 20:08 | comment | added | ttyridal | I'm not sure I understand how I should implement what you're suggesting. May I ask for an illustration? I can't really do anything with the shunt. It's connected between negative battery terminal and the load. my circuit has ground at the negative terminal. | |

| Jun 9, 2017 at 19:03 | comment | added | ttyridal | Yeah. I've actually done a second design with ina199 after suggestions in another answer here on se. At this point this is purely academical to improve my op amp understanding. Would I not still need R3 and R4 for the voltage adder / summing? | |
