Hi,
I was looking at the tda 2030A datasheet ( http://www.st.com/stonline/products/literature/ds/1459/tda2030a.pdf) and on page 10, they have a schematic of a active filter tri amp, each amp having the filter on its input. very interesting.
However, the circuit is designed around using a single source 36v supply.
With my limited electronics knowledge, I cant figure out how that works, considering that the chip's max is 18v
Could someone, point me in a direction where or how I can learn more on what they are doing to give the chip the correct voltage?
I guess the filtering will also work if the seperate amps were powered from +/- rails?
Thanks a bunch.
Travis
