I am new to comparators and i am having trouble finding the one I need. The power rails are +-15vdc, prefer two comparator per package. Surface mount, something like an SOIC8. The output needs to be CMOS rail to rail, so the output can go close to the positive or negative rail depending on input. I may be able to do this with an open drain or collector but I am not sure. The input will be comparing two DC voltages to check for polarity. Input voltage offset may be an issue, as the DC voltage is in milivolts. Anyone know a comparator that can do this?
