Ltspice opa189 behaves strange

[bittumbler]

Hi,

i am trying to simulate a filter. The schematic is from Analog Filter Design Tool (tools.analog.com), but i changed the opamp.
"out2" is the filter with the generic "Universal Opamp" from Ltspice. That works.
"out6" is the same filter with the opa189 (.lib file from TI). This has a totally different behaviour. I dont understand why. I am not anywhere near the limits of OPA189 (i think).

TIA

You got the power supply connections wrong. The basic universal op-amp model doesn't use the power supply rails, which is why it worked.

Why not just paste the model file into the schematic and use the opamp2 symbol, rather than uploading it separately?

Ups. Thanks for your help.
I left the .lib model file separately, as it is quite long/complex and supplied in that way from the vendor.
The images in your attachement, can these be created inside Ltspice, or are they just screen grabs? I found only "print to pdf".

There isn't a way to export to PNG directly from LTSpice. It's possible to copy to the clipboard. Click Tools, Copy Bitmap to Clipboard. I just pasted them into Gimp cut away any empty space and reduced the colour depth to 256 colour or less, to make the file as small as possible.
