[sdiy] Odp: In search of a reasonably precise comparator output

Use comparator with push-pull output, like for example dirt cheap TC75S57 from Toshiba and possibly hundreds of other models.  Or follow regular old school comparator output with logic gate, preferably LV family for better drive capability. Or as mentioned already SPDT switch tied to GND and +5V   Roman  Dnia 20 czerwca 2018 17:14 Guy McCusker <guy.mccusker at gmail.com> napisał(a):  Hello,  I am "designing" (i.e. cobbling together) a circuit in which I need a  comparator whose output is fairly accurately 0V or 5V.   I can think of many ways to do this. Some are very stable (at least on  paper) but appallingly complicated, which is bad because I need at  least 7 of these;  some are very simple but rely on careful trimming  of the saturation voltage of an op amp, which I would rather not do  for reasons of reproducibility.   It is 100% likely that someone on this list has a very simple and  solid way to do this, so rather than reinvent the wheel I thought I'd  ask... how would you do it?   (What I really want, in fact, is to take an input voltage X and output  X if X<=5, or X-5, if X>5.)
