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.
- Page 63 should say “(a) Resistor R1 in circuit 2. Record this value on page 67.”
- Page 63 should say “(b) Resistor R2 in circuit 3. Record this value on page 68.”
- Page 63 should say “(c) Resistor R3 in circuit 4. Record this value on page 68.”
The following parts of lab 6 have been modified from the published version of the lab manual.
- Circuit 6 has been modified. You will be given an updated version of this circuit at the start of the lab session. A GIF of how the circuit works is shown below.
