TDA2030A

[GigaJoe]

Figureout finally ( probably, I think ... , maybe)

so TDA2030A - obsolete , but still a lot on market (as relabeled) and, I find-out a Chinese clone actually as :
YD2030A
CD2030A
UTC2030A
D2030A
it was designed in 2004 ... and still in prod.
PDF: basically translation of the original TDA2030a , absolutely the same numbers/parameters ...

there are 2 diff packages, or 2 diff manuf. (or maybe 3 diff ...)



the good thing:
it definitely not a fake or counterfeit chip 
and it would be fun, as soon as I will receive a package,  due to cost around  12 cents per chip ....

(interesting ....  wonder if possible to use it in a  power supply,  like make a power supply, or splitting , or even 4-quadrant .... hmm )

I've used loads of the TDA2030 amplifiers for radios, test amps, even an AM modulator. They're not 'HiFi' by and reasonable standard but they're pretty good for the price.

Will be interesting to try a few of the Chinese clones (I probably already have if they've been remarked as ST),
