The following options are generally not recommended due to  
the possibility of degraded noise performance of the device:  
the RTN pin can also be tied to an external resistor to reduce  
the gain but performance may degrade due to increased  
noisefromtheexternalresistor. AlsoRTNcanbeleftopenfor  
unity gain mode, however, noise will increase.
