LM2907-N:LM2907-N frequency TO voltage conversion range

Part Number: LM2907-N

I want to convert frequencies in the range 0-20KHZ to voltage. The frequency range is not visible in the DATASHEET of LM2907-N. Can you tell me how many KHZ can be converted?

    LM2907-N works well for lower frequency F-to-V conversion. For 0-20kHz, it depends on your frequency to voltage conversion requirements, it is possible to do up to 20kHz (this is the high end of F-V conversion), then you have to consider the linearity errors that the application is able to tolerate. The datasheet is only specified up to 10kHz. 

    You may also consider LM331, it will work better for higher frequency with better non-linearity. 

      

    If you have other questions, please let us know. 

    Best,
