F find_beat New Member May 31, 2012 #1 I have a problem with the comparator when there are equal inputs to the pA - > + : output is negative + > - : output is floating I want it to that - = + : output is also negative How can I do this?

Click to expand... hi, Please post a circuit. Are you asking about digital or analog comparators.?
