I want to design a board using AD7961. From data sheet I have the following information regarding voltage reference options .however I want to know in which mode/voltage I will have the best performance:


datasheet page 17:

Data sheet page 4:


So I have following questions:


Which reference mode (internal or external) is recommended for AD7961 ?


Which reference voltage (4.096, 5 v or 2.048) is recommended for AD7961 ?
