Does anybody have models of these two power opamps?
Jarno.
I have never SPICED, myself.
I read data, datasheets, looks at curves in diagrams.
Then I use my calculator.
And lots of paper and pen.
Spice or not, we still can get some (disappointing!) surprises,
when we do the real life setup.
SPICE for TDA2050/TDA2040 LM3875/LM1875?
I am 100% sure there are several guys here at Fourm,
that have such data.
I bring your thread to top now - then we see

Here's all the data from National regarding LM3875:

Spicy-models, indeed, but no spice data.

Jarno,
I think I have one of these ICs in my simulator. When I come home today I'll try to obtain the spice model for you.
BTW, you guys have seen the thread about a free and UNLIMITED simulator + pcb (AutoTRAX eda)? I saw it yesterday and downloaded the soft. At a first galnce it seemed very nice.
