Ok i was thinking of using a microchip MCP1541 4.096 vold ref for my
pic, would i be able to split off the 4.096 to a 100ohm voltage divider
to a summing amp or would this be too big of a drain? or would i be
better off passing through a non iverting amp then to my summing amp?

i need the 4096 for my a/d converter but also need to offset another
reading for 1/2 so i would like to kill 2 birds with one stone, bot
signals have to be good, if i split down the 5v to 2048 i'm worried it
may not be as constand as the 4096 supply... any advice welcome


thanks
