LtSpice: failed to find dc operating point right after adding sallen-key High Pass filter

Category: Software

Hi forum,

I have a problem with AC Analysis in my unfinished EMG amplifier circuit , Transit is working well but AC Analysis stop working when i added sallen-key filter (circuit on the right side).

I don't know why. I'm using third party elements from Texsas Instruments.
