Simple Frequency Voltage Converter Circuit Diagram - This is the basic recurrence voltage converter circuit outline. Teledyne Semiconductor`s Type TSC9402 is a flexible IC. Can it change over voltage into recurrence, as well as recurrence into voltage. It is hence famously suitable for use in an extra unit for measuring frequencies with a multimeter.

Just a couple of extra parts are required for this. Only one adjustment point sets the focal point of the measuring reach (or of that some portion of the extent that is utilized most oftentimes). The recurrence corresponding direct voltage at the yield (pin 12â€"amp out) contains impedance beats at levels up to 0.7 V. On the off chance that these adversy affect the multimeter, they can be stifled with the guide of a basic RC system.

The yield voltage, U0, is ascertained by: tfo=C/rei(Ci + 12 pF) R2fm Because the inward capacitance frequently has a more prominent worth than the 12 pF taken here, the recipe does not yield an outright esteem. The circuit has a recurrence scope of dc to 10 kHz. At 10 kHz, the recipe gives an estimation of 3.4 V. The circuit draws a current of not more than 1 mA.
