    Hello,

    I am working on a frequency to voltage converter circuit based on the LM331 IC. I am just wondering if there is away that I can improve the output response of the circuit. I am basing my design on the F/V circuit, figure 6 page 10 of the datasheet.

    So as an example of what I am asking for is as such;
    Lets say there is a Fin=10khz and the Vo=10V.
    but as I decrease the frequency from 10khz to like 7khz, the response is not too fast.
    Not just that particular increment that I mentioned but any decrement, I would like to get a faster response.

    Does anyone have experience with this chip that can help.
    Or should I try the next circuit in the data sheet figure 7?

    Thanks!

    See Fig. 3 in this app note for a fast f-V conversion technique.
