Hi, are you able to share more about the power efficiencies of each type of sensor? Some cursory browsing of TI datasheets gives me the impression that both types use a similar amount of power. I may be missing some context, though.
I did also find this cool report there. Could be pertinent, although from what I understand of the technology I don't see why you couldn't use the same techniques to save power with a digipot.
You're absolutely right! Dreamcast and Saturn make a very good point: The major players are dragging their feet way longer than is warranted.
