hello is it possible to get high precision current measurement (0.1uA to 1A) with a low value shunt resistor?. |

If you want a precision of 0.1 µA it means you want to tell the difference between 0.9999999 A and 1.0000000 A Have you thought about what you are asking? |

Hi IanB, I developed a circuit with shunt resitors 25K ( 0.1uA -0.1mA),250R (0.1mA-10mA),2.5R (10mA to 1A).I got result with these resistors .But i need a low value resistor to read all the current to use in a closed loop.Can you please tell me about any method to achieve this (0.1UA to 1A)measurement . |

No. Especially with a small value resistor. |
