ADA4938: Max values for Rf and Rg Resistors

Hi All,

I was wondering if there is a maximum value for the resistors Rf and Rg ? These resistors are used to set the gain of the ADA4938 amplifier.


I would like to set both of these resistors ( Rf and Rg) to 3 kOhm. 

This should allow unity gain but also give me the correct differential input impedance for my system.

Is this acceptable?


thanks and regards,
