[sdiy] Comparator = Opamp ??

[Peter van Hamersveld]

A comparator is a digital device that outputs a 'high' signal (logic 1 or about 4 to 5 Volts), when the voltage on the + connector is higher than the voltage on the - connector. If the one on the + is lower, it outputs a 'low' signal (logic 0 or 0 Volts).

An Opamp has exactly the same appearance in schematics, though i get the impression (from Circuit Maker 2000 (simulation software)) that it behaves differently. Can anyone tell me the difference, or state that they infact ARE the same...

tnx, thanks, tanx, thanx, tanks, tnks, thnks   (choose your favo-spelling)
