I'm trying to build a second order low pass filter using OPA4228 and when I run the AC Analysis of the filter I keep getting the results that I should get if I had built an high pass.
In fact, if I exchange the OPA4228 with another opamp (NE5532 for example) the results of the AC Analysis are correct, so I'm sure that my circuit is well made.I get this error even with OPA228.
Can anyone help me fix this problem, please? (My circuit project is in attachment)
