Hi,
I have an op amp circuit which is meant to trigger when an input signal goes above a reference voltage of 12 Vdc. The input signal (Vin) is not grounded to my op amp circuit, which makes the input floating.
Of course, the true fix to make this work would be to ground the input signal to circuit ground, however it is a bit more complicated than it sounds...
Therefore; Can I 'drag' the Vin floating input signal to my circuit ground (or close enough) using a Positive Diode Clamp as seen in the picture?
If I can clamp Vin, then my op amp circuit should work as designed.
