In-lab Tasks:

1. Build the buffer circuit and connect it to the DAC you built earlier. Test your circuit by measuring the voltage level generated by the buffer and the voltage level generated by the DAC for each of 8 possible output voltages.
2. Build the comparator circuit and connect it to the buffer. Test your circuit by measuring the comparator's output voltage as a function of at least 10 different reference voltage levels between 0 and 9 volts. Repeat this test for each of the 8 possible voltages that can be generated by your DAC.
3. Build the clamp circuit and connect it to the comparator. Test your circuit by measuring the clamp's output as a function of at least 10 different reference voltage levels. Repeat this test for each of the 8 possible voltages that can be generated by your DAC.
4. Measure the threshold voltage where the comparator/clamp circuit transitions from zero to 5 volts as a function of the reference voltage for each of the 8 possivel DAC voltages. Make a table of your data.
5. Describe what happened in the lab.
6. Demonstrate your circuit to the TA. The TA will double check the correctness of your results and completeness of your lab book, sign off on the book and let you move on to the next lab. You may be asked to redo some of the tasks if they are not correct or complete.
