I\'ve used op amps as comparators a number of times because of the easy availability (they can be purchased 4 op amps to the IC package) so one was used as a comparator while the other three for other purposes. But there are units made that are actually called comparators. Is there something different about these - not just ordinary op amps?

Solution

there is no difference it is just ordinary op amps
