    PSoC3 - Low voltage current monitoring using shunt

    normand.leclerc

      Hi,

         

        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.

         

       

         

      Thanks
