Day 10

Today we went over the different types of components we have used in the past ten class meetings and learned about op amps as well as did a lab with an op amp.

Above is a list of circuit components we have used so far.

Once we learned how op amps work, we treated the op amp as non ideal and redrew the circuit to incorporate as simplified internal to the original circuit. We then used nodal analysis to solve for the ratio of the output and source voltages.

Next we did the Inverting Voltage Amplifier Lab. The purpose of this lab is to examine how the input voltage is amplified using an OP27 op amp.

Above is our circuit layout and our data. We can see that the op amp has a voltage saturation limit at about 4.5V. The linear portion of the graph demonstrates the best operational range for this op amp. The percent error greatly increases when you go past the linear portion as expected.
