MAX186 ADC and Propeller

roverx

I'm thinking about moving my bs2px controllers (redesigning) around a propeller using one of the proto boards with 3/5 volt regs. Just getting into the Propeller, I'd like to know how difficult it would be to use the MAX186 ADC (12bit/8channel) with it. Reason is that aI have a bunch in use, and would not have to swap em out for something else.

Any ideas or proposed connections appreciated.

Meant to add the MAX186 is 5 volt.

I don't think it would be a problem. Just don't wire its outputs directly to Prop pins, put a 1k-2k current limiting resistor between 5V outputs and Prop input pins.

You don't need them for Prop outputs that go to input-only 5V pins, but you also need them for bi-directional pins. Hope this helps.

Thanks, sounds simple enough
