INA260: Can I measure the negative voltage use the INA260？
Part Number: INA260
I would like to measure the current of a negative voltage (-12 V) coming from an ATX power supply. I found an earlier answer on this forum for measuring the current of -5 V, but when applying this solution to -12 V, this would violate the maximum supply voltage VS.
The earlier answer can be found here (how to cope with -5 V):https://e2e.ti.com/support/amplifiers/f/14/t/705892
The best guess I have is below schematic using a positive linear regulator to lower the supply voltage from GND to -7 V (effectively giving +5 V between VS and GND of INA260):
We are glad that we were able to resolve this issue, and will now proceed to close this thread.

In reply to Wytze Hoogkamp:
Thanks for considering to use Texas Instruments. I think what you have would work. However, you might also consider the alternative of using a resistor and a ~5V zener diode to power the INA260, like shown below.
