LegendBreath Posted November 15, 2005 Report Share Posted November 15, 2005 Hi,I got some chip that is marked -VDC and a +VDC... of course, but how do i do that -VDC do I only use the ground of my power supply, like my power supply is build up that way >transformer>bridge>capacitor and on that capacitor I got a + and a -, well, do I plug those two wires on the chip?Sorry for my "noobish" stage but we all went in that stage one day ^_^ Quote Link to comment Share on other sites More sharing options...
LegendBreath Posted November 15, 2005 Author Report Share Posted November 15, 2005 Its a STK4171 if you need more info check out this post:http://www.electronics-lab.com/forum/index.php?topic=4901.0And if its really a -VDC, what do I need to do that? Is is a special regulator or something like that? Quote Link to comment Share on other sites More sharing options...
audioguru Posted November 16, 2005 Report Share Posted November 16, 2005 This datasheet shows a pic of its pins, a dual-polarity power supply, a typical stereo amp schematic using it and a pcb for it: http://www.datasheetarchive.com/semiconductors/download.php?Datasheet=2007735 Quote Link to comment Share on other sites More sharing options...
