Postlab Requirements
- What was the biggest challenge about doing this lab?
Discuss this as part of your summary. Operation amplifier data sheets, like most data sheets contains a general description of the device, a pin diagram, maximum ratings list, and a list of input/output characteristics. Op-amp data sheets also contain an internal circuit diagram which is beyond the scope of this course. The best data sheets also contain sample op-amp circuits which can be very useful.
For each of the data sheets listed above, do a comparative analysis of the notation used by the data sheet
- for the inverting and non-inverting input voltages,
- for the output voltage,
- for the supply voltages,
- for the voltage gain.
Compare these to the notation we will be using (same as text). Record your results in a table. Include a column which gives the general equation for the output of an op-amp [ Vo = Av (V+ - V- ) where Av is the voltage gain according to the text] rewritten in the notation that would be appropriate for the data sheet
- Summarize what you learned doing the lab.
I
strongly
recommend that you do this within 24 hours of completing the lab.
You are summarizing the lab experience not the assigned readings.
The summary should be:
- in point form
- in your lab notebook
- maximum 2 pages.
- Op-amps can be destroyed when improperly handled. What would be a quick simple way to test the operation of an op-amp?
- Photocopy your summary and submit it along with the question answers to the instructor at next week's lecture.
