Op amp followers look at an input voltage and provide the same voltage at the output. The op amp output provides the power to the load so that the input voltage doesn’t get thrown off.
I use many of the integrated circuits from this kit in my videos.
A dual or split power supply has both a positive and a negative voltage in relationship to the zero volt ground reference point ground. Many op amp are made to be used with a dual/split power supply.
Some nice low power boost converters above that I enjoyed using in a couple videos.
