How to implement flexible gain settings using the ADA4960-1

Question

The ADA4960 datasheet mentions: 
 "The buffered inputs of the ADA4960-1 isolate the gain-setting 
 resistor (RG) from the signal inputs, maintaining a constant 10 kΩ 
 input resistance, easing matching and input drive requirements." 
 Does this affect the behaviour of the feedback resistor? Can I use several gain resistors switched by a coax relay? 
 What is the best way to implement 2 or 3different gain settings?

Hi, Anna, 
 Yes, thank you very much for your help. I will set up my design using a set of relay switched gain resistors. 
 Best regards
