Circuit diagram of frequency to voltage converter An on-chip zener clamp produces a regulated and stabilized frequency to voltage or current conversion (only in LM2917s) A typical connection diagram of the IC LM2907/LM2917 is shown below: Using IC LM331. Another simple frequency to voltage converter can be seen in the above circuit diagram, using a single IC LM331. The project goal is to design an embedded system (hardware/firmware) that takes in a frequency input signal. Maybe from a motor encoder or whatever and measure the frequency then convert it to analog voltage signal at the output. Of course, F/V converter integrated circuits (ICs) and other solutions are viable options indeed.
This IC is basically a voltage to frequency converter, but we can also use it as a frequency to voltage converter. Its applications also include analog-to-digital conversion and long-term integration. F-V Converter Working. In this circuit, LM331 converts frequency into voltage. The voltage on the output is proportional to the frequency at the

A Simple LM331 Based Frequency to Voltage Converter Circuit is an easy and efficient way to measure frequency and turn it into voltage. This circuit works great for things like speed sensors, tachometers and systems that control industrial processes. You can tweak the output voltage to fit your needs by changing the values of R4 and C2. Theory of Operation Qualitative Description. The circuit operation is fairly straightforward. When the input signal goes low, C 1 charges through D 1.It is critical that C 1 charge quickly relative to the period. This circuit depends on the transfer a fixed quantity of charge at the same rate as the input signal. IC LM331 Family of Voltage to Frequency and Frequency to Voltage converters are ideally suited for use in simple low cost circuits and applications like, analog to digital conversion, precision frequency to voltage conversion, linear frequency modulation or demodulation, and many other functions.

At its core, a frequency to voltage converter circuit diagram is relatively simple, and consists of three basic components: an oscillator, an amplifier, and a rectifier. The oscillator is responsible for generating the high frequency signal that will be converted.

in a very simple linear relationship. In our application Vcc = 5V and we wish to see a maximum output voltage of 5V as well, therefore we are given a simple design equation relating our component values to the maximum expected frequency of our input signal. (3) Choosing a value for is relatively trivial. For low frequency signal acquisition the
