While trying to find out a realistic maximum power consumption target I was searching for the power consumption of the LPCOMP comparator. I've seen a few claims about 0.5 µA here in the forum but the only reference I could find in the documentation was this table:
ICOMP,LP |
COMP enabled, low power mode |
30.1 | µA | ||||||
ICOMP,NORM |
COMP enabled, normal mode |
31.8 | µA |
Now, I don't think that a reduction from 31.8 to 30.1 mandates calling it "low power"! I suspect that table does not mean LPCOMP but rather the regular COMP in some special mode?
I also found this unanswered post claiming that it takes 20 µA in practice.
Is the LPCOMP power consumption actually stated anywhere?
