CONFIGURATIONS

Figure 36 and Figure 37, along with Table 6 and Table 7, provide

examples of the possible input and output ranges for various

supplies and reference voltages.

Note that Table 6 and Table 7 list the typical voltage range of the

AD8275; these values do not reflect variation over process or

temperature.
