good day to everyone again. i would like to ask if someone could explain the logic behind this frequency to voltage conversion, for tachometer application with analog output. my input is signal frequency and i need an output in voltage. The circuit is using the IC NJM4151 (attached file).
The input is fed in pin 7 and the ouput is at pin 1.
Just would like to ask what is the formula that would invert a frequency to a voltage using this IC or perhaps other IC that has similar application.......
