Newbie level 4
VCC=5V.
I am trying to condition 4-20mA analog signal.
I ma using a current sensing resistor of 47ohms to convert current to voltage.
at 4mA i get 188mV and at 20mA i get 940mV.
with a gain of 2.7, i must get 0.507Vand 2.53V at 4mA and 20mA resp.
but i get 0.3V and 0.6V as output.
I am not able to get expected output.
I things this is because of some grounding issue(Analog and Digital ground) but not sure about it.
Can some1 suggest me something.
