D dch222 Member Apr 4, 2007 #3 5 pins when you include the power pins. Most op amps are like this so you shouldn't have any trouble finding one.

It wouldn't really be much of an opamp if it only had a single input - it would have to be an opamp pre-wired to a particular configuration in which case I think the overall device would be called by a different name - buffer, amplifier, etc.
