Ex: I'm sort of looking at the Intersil/Vishay DG409, but it
appears to require +/- supplies.  Anyone have any experience with 
it?  Will it run well either single ended, or with a trivial
negative charge pump?  (I've got a car battery, so it's a 
decent PLUS supply...)

If not, are there any DECENT analog switches out there that run 
well from single ended supplies?

OR, is there a SIMPLE trick to generate enough clean, balanced
plus/minus supply from a small robot, to run a dual supply amux chip?

Thanks!
