You've got four comparison channels to wire up and you need a chip that draws minimal current while keeping your logic clean. The LM339 does exactly that: a quad low-power comparator in a 14-pin package, ready to slot into your breadboard or PCB. No extra biasing headaches, no mystery datasheet rabbit hole. Grab it, solder it, and get back to the rest of the build
