Thanks for the reply Dale. That is basically what I want to do. Would I
achieve any advantages to using a fixed resistor on one side? Obviously
your method wins in the parts number contest. Also, shouldn't that be
ends to ground and Voltage Reference? In this design it won't make a
difference, but just to be clear for the future. Also, can anyone
reccomend any analog multiplexer chips? Basically I want to read more
than 8 potentiometers. At the moment, it'll probably end up around
12-24, but could be higher in the future. I'd like to stick with the ADC
build into the chip, but multiplex the inputs. Any ideas?

Thanks,

Josh Koffman
