Product Number: MAX4081
Software Version: LTspice 24.1.10
hello. I'm trying to evaluate how a max4081s would behave in my circuit using the ltspice model from the product downloads page. It doesn't appear to be working as described in the datasheet (e.g. bi-directionally). In addition to that, the reference inputs don't appear to be behaving as described. The datasheet says if you ground refB and give refA a potential it should bias to refA/2. Or as in the attached image I gave both pins 6V so the reference should be (6+6)/2= 6V; but as you can see its output is biased only ~4.2mV. It also appears to be ignoring polarity in terms of phase alignment. It doesn't seem to make a difference if I reverse the leads on RS- and RS+, it's always inverting the output.
