I am doing a project on strain gauges at school. The output of the strain gauge is dc, and the output ranges from 0.05mv to 1 or 2 mv. I would like to boost the signal to like a range of 1 to 10 volts. I have tried using a 741 opamp to do it. However, it seems that the Noise is quite high. Does anyone know how i can boost the signal without very high noise? Thanks.
