Hi everyone,
How can I calculate the gain parameters of a differential amplifier?
I am measuring temperature in the range of 300 degrees and the output from the amp should be between 0 and 1 V. How can I calculate the gain factor from this information?
Thanks, D
I realize that I did not understand this properly and gave nonsense information:
Now the difference of inputs is 0.0075 volts Ther output is in the range 0-1 volts I have calculated that the gain should be 130.
Now, I need to find R1 and R2, so as to get this gain. What formula should I be using?
Cheers, D
Ok, I see the following formula:
V(out) = R2/R1 * (V2 - V1)
So, R2/R1 = V(out)/(V2-V1) = 1.0 / 0.0075 which is approximately 1300, which is my gain value...
So R2/R1 is the gain value in this amplifier???
