You have a DC path to gnd in the - input line...data sheet has a cap in there.

thank you
but the connection I drove is good, it is take after an output cap, and please remember, this is transconductance amp so its connections are different than application note.
bellow corrected spice directives...

I think DUG is correct, you have a direct ground conection to the inverting input. It doesn't mater that the output is AC coupled, the input pin is still ground referenced.
(your .asc file wont run on a default LT installation. There are unknown models and subcircuits being called up that aren't included in your file)

Pawel please post a schematic of your work for people to see that dont use simulators
Thanks
Of course I will
but I still cannot run proper simulation, to check if this has a chance of working good🙄
please advise

please nurse me
how to create
sub and asy
circuit of TDA2003
on the base of the model as in above post.
thank you in advance!

Hi
the circuit should look like this: http://www.diyaudio.com/forums/atta...nductance-current-amplifier-tda2003-trans.jpg
as reported in that thread the amp is working
hope this helps
