I am using AD628 for my current sensing application .Current range 0 to 2.5amps through the R76 (0.01 current sense resistor ) . the gain for first stage is 0.1 and second stage is sate as 3.12 , supply voltage for the AD628 is +5V and GND (single supply). while measuring the 1st stage output at C512 (by varying the current from 0amps to 2 amps) , I am always getting 0.715V and second stage 2.174V . whereas the expected voltage level should be as below .
|Current(amps)||Expected output @ 1st stage of AD628 .||Expected output @ 2st stage of AD628.|
Kindly address the same issue .
