    Hi Jigar, Jigar Jain said: But i dont understand why this is not working in simulation model ? When you say simulation model, you mean TINA-TI / PSpice simulation? These models are not designed for replicating the common mode vs output voltage plot.…

    Hey Ben, No worries! Yes, adding a sufficiently smaller third resistor will cause the smaller resistor to dominate the error analysis. If you are looking at how to add in an integrator, the easiest method would be to buffer the mid-voltage point. This…

    Okay, so as expected, poorly-designed off-the-shelf filtering - thanks both of you. The TINA simulation indicates it's better without and removed them on one board and not really seeing any improvements so still trying to work out the dependent variable…
