    Hi all,
    I need some help in voltage to frequency converter. ie, the input to the system is a varying voltage between 0 to 10 volts and the there should be a corresponding variation in the frequency of the output waveform.

    Can anyone briefly explain the priciple of this converter? Also it'd help a lot if you provide a schematic of the same...

    Thanx.

    Get the data sheet of an LM2907. It's a handy IC, as it works both ways - F to V and V to F.

    How do you make a V to F with LM2907?
    Silverscorpion, I'm assuming you did a search. I find it hard to believe the information you want is not readily available.
    EDIT: The LM331 datasheet includes the theory of how it works.

    Hi, I would recomend IC 4518. Years ago, I made a frequency-voltage converters (for my tester) it work fine, also can make voltage/frequency.

    The only 4518 I can find is a dual BCD counter, which isn't even close to what the OP wants. Do you have a more specific IC number?

    Sorry, I must say XR 4151.
