A transducer used for temperature measurement in a chamber provides an output of 5mv/ C. The range of temperature measurement is from 0 to 100 C. A 6bit-A/D converter is used. Reference voltage is 12volt. Find the input voltage. Design an A/D converter to provide the required temperature resolution.
What will be an ideal response?
The transducer output at 100 degrees will be = (5)(100) =500mv. An interface with A/D is designed such that at 100 degrees, the output of A/D will be 111111. The required input voltage is calculated as follows:
The A/D converter has a range of 6 bits and hence 
different values of the input voltage can be represented. A typical voltage given is 12 volts. Therefore, the resolution would be
