Based on the simulation, the TDA2030 will draw about 14.4A at 12V to produce a 20W output (at R16ohm) with an imput before Preamplifier(BC547 BETA 127) of 0.1mV at 1khz. Its seems that the preamplifier gives a good output(about 220uA Ipp with a Vpp of 4.5Vpp,wich is good enough to power a speaker) and the TDA2030 just goes crazy high
You must have input some gross errors because it is absolutely impossible you get "127W" at TDA2030 out, not even 19.2Wavg from mere 12V single supply into 16 ohm no less.
Neither 4.2A , 21W into the chipamp, "191Wavg", etc.

i absolutly thought the same, but i double checked, and the problem starts only when the imput (At 2030) is(see image), any value higher makes the Current of the 2030 go higher and higher, and the output power at 16 barely increases
Hello MG,
I think you are posting in the wrong section do please try the Chip Amp section.
Briefly C&P'd
The TDA2030 is a monolithic integrated circuit in the Pentawatt® package, intended for use as a low frequency class-AB amplifier. Typically it provides 14 W output power (d = 0.5%) at 14 V/4 Ω. ... The TDA2030 provides high output current and has very low harmonic and crossover distortion.
Cheers

Pin 3 should directly be connected to ground.
... Indeed an (old) class AB amplifier, no class D.
Errrrrr is it obsolete, of course not!

ST and later UTC Taiwan were the last 'original' TDAs, I think Philips was the first.
The ones from CRC China are good, those with ST markings are fakes.

Well.... thanks for the feedback, i found a solution, it was caused by the powersupply, the input signal caused by an unkown reason (for me) the DC signal to also generate an AC signal of current, this moving current was removed by the simple inclusion of an LM7812.. the power output now is around 20w at the resistor and 25w at the 2030

In any case,there is a gross problem (or many) in your simulation,which you must find.
A plain TDA2030 MUST simulate perfectly well, with no need for bandaids.
definitely here is not the proper area; at least re-ask in the chipamp section, but Even better in some Forum area (Software problems?) focused on simulation; we have quite a few Gurus (in the good meaning of the word) here.
I think Mooly is one of them, spreading the Spice word 🙂

Again: you do not have a TDA2030 problem, you have a simulation one.
Maybe a moderator can move this thread there, self report your first post to get their attention.
