Lab 6: Operational Amplifiers

Lab 6 will come from the published version of the lab manual.

Suggested Pre-Lab Activities

Completing the following activities before attending lab will save you time during the lab session.

You are going to be working with DIP chips in this class, which is very different from other circuits you have built up until this point. You may want to consider drawing pictures of how to connect your circuits based on the pins of the DIP chip. Or, you may want to use TinkerCAD to play around with the op-amps and build one or two circuits online before coming to class. You can use your TinkerCAD layout to help you out when you are in class.

Lab Manual Errata

The following are known errors in the lab manual corresponding to lab 6.
