my design is 350 ohm half bridge strain gauge with 5v as an input.
i used the following amplifier circuits. still now i get unstable voltage at output.
i designed the amplifier circuit with 100 gain, using ic 741 as an opamp
Rf=100K; Rg=10K; R1=R2= 1M; R4=R3= 4.7M
so suggest me what do to scale 1mv to 1v
