Maybe you can selectively turn the filter on/off for different ADC channels?
Also, the Arduino code for that Parallax switch indicates they are using 5 digital inputs, not one analog. I haven't taken a closer look at the specs to see if analog output is an option, but their page only mentions "a 10k resistor", which doesn't sound promising.
