lol no, maybe you're thinking of the Harris DG* analog muxes
one can find plenty of 5V (or less!) analog switches with excellent R(on) on the order of 10 ohms at 15mA, even in grandpa-friendly 1.27mm SOIC packages. the SN74CBT3253 dual 4:1 mux, for example, would suit this application nicely if a proper digital pot is unavailable (which surely it is not?)
