Uhm, no... because it was JUST A SUGGESTION. The reasons were given in my reply. As well, for the reasons given in my reply, i can't select a part number because i don't know the parameters of his project. I don't understand why you're being so persistant about this?

I suppose that "better" is highly dependant. For some people, a geo metro is better than a Enzo Farrari... but the farrari is definately more complicated, costly and difficult to build. I think in terms of accuracy and reliability. You will get better accuracy if you do not leave it to resistive dividers and instead use ADC's specifically designed for the intended voltage range.

If it is a quick and dirty hack job you are looking for, then by all means use an analog multiplexer and resistive dividers... whoever is paying for it may want better.
