Analog Multiplexer Using ADC

Is it possible? Feasible?

Depends what you mean?, your post doesn't make any sense.

You mean reading various analog signals and multiplex to an ADC? Sure there are lots of examples . Search for the Basic Stamp (I know there are better devices...) there is a project on using the CD4051 multiplexer and one ADC (ADC0831). I have done this myself and works perfectly.

Analog Devices has 12 channel A/D chips.

Except it's only single channel, with a 12 to 1 CMOS switch internally, just like PIC's only have a single channel, and an internal analogue switch. But we've still no idea what he wants or what he's asking?.

Yup, that's exactly what I mean... Thanks

Then choose a PIC (or other micro-controller) that has it all internally.

Owkie will do Thanks
