TDA2030 as op-amp

pra3718 · 18th March 2010, 10:47 AM

As per attached picture first-top amp may be act as high pass & bottom-2nd amp as low pass. 1st amp is 2nd order HP & 2nd amp is 1st order LP. While connecting speaker it may act as HP&LP mixer. 1st amp output 15watt & 2nd amp's output 30watt.

I did not build this. I want approval, how does it sound ? advantage & disadvantages. Anybody worked on this

Try drawing a proper schematic, with all the pins of the TDA2030 properly labeled, and you may get a response. The image you've uploaded doesn't show a schematic.

Try Looking in the TDA2040 Datasheet , it shows you how to do this properly and even has a PCB design ......
