Hi,
I'm have a circuit that I want to replace some op amps with TI pars. I have the whole circuit already simulated in LTspice, but I can't get the imported OP-AMP to work in simulation. I get
ERROR: Node U1:I0:I0:I19:1:102 is floating and connected to current source G:U1:I0:I0:I19:1:RA
ERROR: Node U1:I0:I0:I19:1:302 is floating and connected to current source G:U1:I0:I0:I19:1:RC
ERROR: Node U1:I0:I0:I21:1:102 is floating and connected to current source G:U1:I0:I0:I21:1:RA
ERROR: Node U1:I0:I0:I32:NET8 is floating and connected to current source G:U1:I0:I0:I32:RCMFBAVG1
I tried saving the model as shown in
but no luck.
I have done this before with lmh6550 and it simulates no problem. But the files, when i inspect them in text editor, are different in structure. See both files attacked.

Is there a way I can import/convert the THS4551 model? Or am I just importing it wrong?
