1. The problem statement, all variables and given/known data I need to set up a blueprint for my instrumentation amplifier on a breadboard shown on page 5 of the attached document 2. Relevant equations 3. The attempt at a solution I'm not sure how 2 op-amp chips will make 3 op-amps for the instrumentation amplifier. I'm also not sure how the figure on page 2 comes into play when creating the circuit on page 4. I don;t know where to attach grounds here is what I have drawn so far for my amplifier circuit, I don't know where R4 should connect if there are only 2 omp amps and the diagram has 3.
