Problems for ADA4960 Single-Ended DC-Coupled input style

I am using the ADA4960 as the ADC driver.

     1 The resistor connects to the VIN pin is 25r according to figure 40 which is different from the 50r in figure 32. So, which one is correct?

     2 The DC value of the input signal have to be within the common-mode range which is from 2.25 to 2.75 Volt? If this condition is not satisfied, the

        AC-Coupled style must be adopted?

 

Thank u for help~
