Hi all, I am trying to build a circuit for driving multiple LEDs under test at a given current, and the LEDs are to be individually tested with multimeter. Now I know I could just run them all in series and they would get the same current, but if one LED breaks, then the whole circuit goes down. I was thinking of using a current mirror, but I have not really worked with them before and am not sure if I can chain them together i.e. a single reference current to drive them all, with a common voltage source driving the rest, and a common ground to all of them, with the LEDs on the 'copy' arm of the current source. the component I am thinking of using is this: http://docs-europe.electrocomponents.com/webdocs/0c5c/0900766b80c5c6ff.pdf if it would help for me to draw a diagram, I can do that! thanks!
