    Looking for some converters: Voltage/Resistance/Temperature to Voltage

    Hi I want following signal conditioner ckt:

    Voltage to voltage converter
    Resistance to voltage converter
    Temp . to voltage converter

    Re: Need Converter

    Please specify your specification of each of your converter?

    Re: Need Converter

    For the resistance to voltage converter. make an oscillator (TTL gate and RC filter) and you can use the LM2917

    The same thing with your temp converter, you can use a varistor in the RC filter of the oscillator ... do you want more information aboute the logic oscillator ?

    For the voltage to voltage there is not a better solution as an Op-Amp (MY opinion, it really simple but it depend of your application)

    Re: Need Converter

    I wnt it with op amp & specification r as follow

    R to V converter ----- 0 - 5 v from 500 to 1000 ohm
    V to V converter ----- 0 - 5 v from 2 to 6 mv

    H ehe eh eheh e !
    the Simpler way than . . . . .
    1. R to Voltage: Why can't you use the formula:
    V = I * R (if I = constant)
    (you should use the IC as REF02, . . . . to reference current).

    2. Voltage to voltage converter :
    This is the DC - DC converter ? if it is right, you should MC34063 !

    3. Temp . to voltage converter
    This is the temp.sensor as LM35,. . . . .


    Good luck for U !
