, *** Important note for today’s lab ***
In today’s lab, you will be building various op amp circuits.
 Using a 741 op amp: a buffer amplifier
 Using another 741 op amp: an inverting amplifier, then a summing amplifier
 Using a L272M op amp: a buffer amplifier

** Very Important: Your wiring should be very neat, or you (and the TAs) will have problems
finding all your mistakes. Look at the below figure for an example of neat
wiring. Notice how there are few wires overlapping things, and that
common power buses are used.
