    PSoC3 - Low voltage current monitoring using shunt




        I am new to the PSoC world.


        I have a project and wish to do current monitoring using a PSoC3.   The system is 3.3V and can drain a maximum of 1A.


        I see that the smallest range is +/-64mV which is still too high for my application.  Draining 64mV on 3.3V will affect the circuit.


        Can I add an internal op-amp to boost the voltage difference before I enter the current monitor block?  Let's say a x10 amplification would be acceptable.
