I am just purchasing all the parts to begin on the PIC Speech Synth project. In the part list it calls for LMC6482 or TLC2272

I am putting all of the rest of the order together on a Rapid Electronics order, but they do not appear to stock either of these two op amps. Can anyone give me a like for like replacement that Rapid do stock? I do not, off hand, know why this specific op amp is selected, nor what to look for in a replacement.
Any quick pointers much appreciated, as it would be a real nuisance to have to move the whole order over for the sake of 1 op amp.

Phoenix, it is a dual op amp which I chose for its rail-to-rail output swing capabilties. Others that do the same could be used. Mine came from RS.

The LMC662CN CMOS DUAL OP AMPLIFIER (82-0394) would probably work okay. It is listed as a dual op amp with rail to rail output, and has the same pin outs as the specified op amp.
