Dear sir,


I am trying to measure the Current the the millivolts that is been generated by Shunt. there are many gain ranging from 1 to 512 for calculating the current, The problem i am facing is while i am setting the Gain for example if i set the Gain as 256 the range should be +/- 4.68mv  since i am calculating the current with keeping Vref as 1.2V, But insteed i am getting completely other range.


So, can u please suggest and help me in measuring the current.


With Regards
