741 op amp circuits video series

741 op amp circuits video series presented below is intended to help those new to electronic get more familiar to using integrated circuits and op amps in general.

I do not have a split power supply, so in the video below, I used a 741 op amp wired as a virtual ground rail splitter. That means it takes the 18V my bench power supply can provide and outputs half the voltage that I designate as my 0 vote reference point ground. In relation to this virtual ground, the power supply now has a +9V and a -9V terminal.
