Op-Amps Application

Introduction
          Op-amps are often used for scaling and level-shifting application. Scaling is simply process of multiplying signal voltage, in this case by factor of the gain. level shifting is the process of adding constant to a signal.in this lab, we will use a thermal sensor that produces temperature reading in Celsius and the goal of this lab is to change the reading into Fahrenheit scale.

Experimental

The circuit that was built is as follow:

The value was obtained through the equation Vf = (1 +R2/R1)Vc - R2/R1 Vref

Vref is dropping the 9V through a potentiometer and crank it accordingly.

The actual circuit built was shown below

Conclusion 
          The experiment was a success as we test the input from the temperature sensor and the output of the op-amps. One of the value tested is room temperature at 23 degree celcius read in 23mV. This gets amplified and the reading in our DMM become 73.4 which is approximately the temperature in fahrenheit.
