I'm building a resistor multiplex circuit that will use a couple of low power Op amp comparators. The comparator outputs will be connected to the IO pins of the MCU. This will be a coin cell powered device with ultra low power requirements. Needs a standby time measured in years, not hours. So even …

Ultra low power switch comparator

Maybe you can use ADC instead of comparators?
