  • RE: VFC32: VFC32

    Resolved
    Hi Willie, figure 2 of datasheet of VFC32 shows what cap values have to be chosen, if you want to reduce the full scale frequency down to 1kHz or even below. However, this will result in cap values which might be unsuitedly large and difficult to obtain…

  • VFC32: VFC32 frequency to voltage converting applications

    Part Number: VFC32 Hi, First, our product system needs to have a chip to well support frequency to voltage converting function with “20Hz to 500KHz sinewave only” frequency input. So, regarding the “TI VFC32” frequency to voltage converting applications…
