my application is weight scale .
as you know about load cell , With 2-mV/V sensitivity and 5-V excitation, the full-scale output voltage is 10 mV.
and in order to use the most linear portion of the load
cell’s span, only about two-thirds of this range would be used.
So the full scale output voltage would thus be about 6 mV.
for example for AD7799 (something that i'm using currently ) the full range is 39 mv(with maximum gain).
So I just use 6mv out of 39mv .
Is there any solution to use full scale ?
Is it good idea to pre amp (by low noise op-amp) ?
