All About Op-Amps

This video is “All About Op-Amps” which explains what an Op-amp is and various configurations such as the Voltage Follower, Non-Inverting Amplifier, Inverting Amplifier, Summing Amplifier and many more examples. We also deal with the “Elephant In The Room” and that’s the issue of needing Dual Power.

If you are new to Op-Amps, then this is a great introduction to whet your appetite and get you going. If you are already familiar with Op-Amps, then you may still find elements in this video that are either new aspects to you or perhaps help to reinforce your current understanding.

The video covers quite a lot of aspects using a mixture of graphical theory & real demonstrations at the workbench. It’s quite lengthy, so you may want to jump to a particular point of interest. In which case, you can use the timeline (chapters given at the end of this description or use the red time bar shown at the bottom of video itself).
