Hello, 

i have to sense the 5 amp current in my circuit . i connect 0.01Ohm resistor across the batter  that i am getting 50mV~100mV that i have to configure as current ... 
i saw one article about Trans-Impedance Amplifier -- Link 
https://www.element14.com/community/thread/26739/l/psoc-4-pioneer-kit-community-project087-gas-senso... 

i got confuse about the connection and how much current we can sense .. becoz that project need updation ...

Hello Deepak,

   

Please use the current sensing method to sense the current flow through the resistor. Either the high side current sensing or low side current sensing can be used in this case.  

   

Transimpedance amplifier cannot be used here, since the current rating is high. 

   

Thanks
