I'm considering a design that would be activated by a capacitive touch switch. The switch circuitry would be the only thing drawing power most of the time at 34uA and 3V. I'd like to run it off of a couple of AAs, and, of course, I'd like to know how long the batteries would last, but the manufacturer data I've been able to dig up doesn't provide discharge curves for such low power consumption. Has anybody performed or run across an analysis of power consumption at this very low end of the curve? Thanks.
