This carries over from a previous thread I made.
I have an op amp circuit designed that works on my test bench, but not in my vehicle. Op amp reference voltage is set at 12Vdc and I have a square wave as Vin. See picture below.
It is thought that the reason for the circuit not working properly is because Vin has a floating ground which is causing the op amp trip levels to act differently than on my test bench.
To fix this problem, can I use a Positive Diode Clamp, as pictured below, in order to bring the bottom edge of the floating square wave to my circuit ground?
