<DIV><SPAN class=538511503-21012025>Hey SDIY Team,</SPAN></DIV>
<DIV><SPAN class=538511503-21012025></SPAN> </DIV>
<DIV><SPAN class=538511503-21012025>I just bought 100 AS3350 dual SVFs for a
massive project. The datasheet is a bit strange. In one place, it
says that the supply can be from +/-3V to +/-16V. In another it says
that the total supply voltage should not exceed 26V. On the diagram, it
says that the supplies can be +3 to +12V and -3 to -12V.</SPAN></DIV>
<DIV><SPAN class=538511503-21012025></SPAN> </DIV>
<DIV><SPAN class=538511503-21012025>So, obviously, they are intended for +/-12V
supplies.</SPAN></DIV>
<DIV><SPAN class=538511503-21012025></SPAN> </DIV>
<DIV><SPAN class=538511503-21012025>My question is this: What do you think
would happen if I used my +/-15V supply? Would it a) work just fine, b)
get too hot, or c) exploderate?</SPAN></DIV>
<DIV><SPAN class=538511503-21012025></SPAN> </DIV>
<DIV><SPAN class=538511503-21012025>Of course, I'll try it out, but if it works
fine and doesn't get hot, is there some hidden catastrophe that will take me by
surprise later? The chip basically contains four exponential sources and
six OTAs. I don't really understand why it should be that sensitive to
supply voltage.</SPAN></DIV>
<DIV><SPAN class=538511503-21012025></SPAN> </DIV>
<DIV><SPAN class=538511503-21012025>In a related question, if I want to provide
a +/-12V supply for the chip, then what do you think about just dropping
15V to 12V and -12V through a couple of opamps and using that as the supply for
the chip? Everything else on the board is perfectly happy with
the +/-15V supply. Alternatively, I could use 78L12 and 79L12, but
I'd rather avoid that if I could.</SPAN></DIV>
