EE 420L Engineering Electronics II Lab - Lab 4
Op-amps II, gain-bandwidth product and slewing

Pre-lab work

• Watch the video op_amps_II, review op_amps_II.pdf (associated notes), and simulate the circuits in op_amps_II.zip.
• Read the write-up seen below before coming to lab.

---

Again, this lab will utilize the LM324 op-amp (LM324.pdf).

For the following questions and experiments assume VCC+ = +5V and VCC- = 0V.

• Estimate, using the datasheet, the bandwidths for non-inverting op-amp topologies having gains of 1, 5, and 10.
• Experimentally verify these estimates assuming a common-mode voltage of 2.5 V.
• Your report should provide schematics of the topologies you are using for experimental verification along with scope pictures/results.
• Associated comments should include reasons for any differences between your estimates and experimental results.

• Repeat these steps using the inverting op-amp topology having gains of -1, -5, and -10. 

• Design two circuits for measuring the slew-rate of the LM324. One circuit should use a pulse input while the other should use a sinewave input.
• Provide comments to support your design decisions.
• Comment on any differences between your measurements and the datasheet’s specifications.

Ensure that your html lab report includes your name, the date, and your email address at the beginning of the report (the top of the webpage).
When finished backup your work.
