IC pins too small for my breadboard
If your IC does not come in a DIP package, you can use a break-out board like this one (Adafruit) and some pin headers and solder your SOIC-16 or TSSOP-16 package onto it to use it in a breadboard. This of course assumes the package you have bought is a 16 pin package - there are other versions of the breakout board available on the internet as well.
