1. The problem statement, all variables and given/known data 2. Relevant equations 3. The attempt at a solution I am working on the prelab for my class right now, and I am having difficulties understanding how to get my Multisim to work. Sadly we have not learned about Op-Amps, and by design our instructor has us do problems involving things not taught in class in order to force us to do research and such, so I am pretty lost with this. On page 2, my pin diagram is the same as the pin diagram on the 1st page of the datasheet at the top left for the TLC227 (D, JG, P, or PW Package) Datasheet: http://www.ti.com/lit/ds/symlink/tlc277.pdf For page 3, I have the ''Positive Supply Label'' as Pin 3 and 5. The ''Negative Supply Label'' is pins 2 and 6. I was able to prove the relationship on page 4, but now I'm stuck on the part about simulating the circuit. First of all, the diagram on page 3 has only 3 connections leaving the op-amp, and the one on multisim has 5 connections, so I don't really know what to do with the other 2. I'll attach the lab, but I am working on page 4, asking for the R_f and R_in. Here is my inverting amplifier, it won't actually run at the moment, something is messed up with this circuit.
