OAP 1 (.
You have an op-amp that is powered at VDD = +5 V and VSS = -5 V. You have resistors to create a voltage
divider, and you can tap into the +5 V and -5 V supplies, but not ground. Design a circuit which will
output +5 V when the voltage from a sensor (Vsense) is greater than 2 V and output -5 V when the voltage
from the sensor is less than 2 V. The voltage divider should be designed such that it conducts a current
of 1 mA. Include a drawing of the circuit and label all voltage sources and resistors that you use with
their respective values. (Hint: Vsense is one of the inputs to your op-amp. Just label whichever op-amp
input terminal you determine should be Vsense with "Vsense." The other input to your op-amp should come
from the voltage divider that you design.)
