I am afraid that you do not understand.  You do not apply amps, you apply 
voltage.  The internal load impedance of the device is something you have no 
control over.  You will only increase the total load impedance by adding 
external resistance, which will be a DC resistance added to the network. 
The only thing you will accomplish by that is reducing the working voltage 
across the chip itself and increasing the noise contribution.  Would it not 
be wise to read a few pages on ohms law to inform yourself?  You do not need 
to delve into AC signal characteristics or noise.  Just familiar yourself 
with the concepts of E=IR (the relationship between voltage, current and 
resistance; volts equals network resistance times network current.
