9.2.1.1 Design Requirements

For these example applications, the input analog signal is differential to illustrate the offset and common mode

reduction merits. An example of the use of an adjusted reference voltage is to accommodate a reduced span or

dynamic voltage range of the analog input voltage is also depicted.
