    Convert output to 0-5V

    after i shift the output to 0.0-4.6V, will that make the output linear. let me explain what i'm trying to say, with an example, i know i get 0.3volts for 20kPa (sensor standard value) and now if i get a voltage = 1.575 volts and solve it as pressure = (20/0.3)*1.575=105kPa, but instead the...

    Convert output to 0-5V

    thanks for replying but in your first solution thru opamp wht should be the value of the resistances to convert 0.3-4.9V to 0.0-4.6V and the second opamp signal by 1.087 to produce the required 0-5V output .. thanks
