Hello all, How should the 1.8V ADC (and other) pins be protected? One method may be the attached, voltage divider of 1M/100K then limited by two diodes in series. (Not tested, just paper design currently.)
I'd like to explore other methods or suggestions. I have some old or obsolete parts that I can use with info from data sheets. But it'd be nice to go "modern". What about VCO to optoisolator? (Think of hostile / automotive applications.) Suggestions: Circuits, books, URLs? Thanks!
