Frequency to Voltage Calculator

Are you looking for a simple way to convert frequency into voltage? Our Frequency to Voltage Calculator helps you do it fast and accurately. It’s designed for engineers, students, and hobbyists who want quick results without manual calculations.

Understanding this conversion is easier than it seems. With a few inputs, you’ll get the output voltage in seconds.

What is a Frequency to Voltage Converter?

A Frequency to Voltage (F→V) converter is a tool or circuit that changes a frequency input into a proportional voltage output. This process is common in electronics and signal processing.

Think of it like a faucet. The faster you turn the handle (frequency), the more water (voltage) flows. The relationship is linear, so doubling the frequency doubles the voltage.

The Calculation Formula

Our calculator uses a standard formula from electronics:

V_out = f_in × R × C × K_IC

Where:

• V_out is the output voltage in volts
• f_in is the input frequency in hertz (Hz)
• R is the resistance in ohms (Ω)
• C is the capacitance in farads (F)
• K_IC is the IC-specific constant

This formula works for common circuits using ICs like LM331 and LM2907. You just need to enter your frequency, resistance, capacitance, and IC constant. The calculator handles the rest.

How to Use the Frequency to Voltage Calculator

Using this tool is simple. Here’s what you do:

1. Enter the input frequency – Choose Hz, kHz, or MHz depending on your signal.
2. Enter the resistance value – This is the resistor used in your circuit. Units are Ω, kΩ, or MΩ.
3. Enter the capacitance value – Input the capacitor in F, µF, nF, or pF.
4. Set the IC constant – Some ICs need a specific factor (usually 1 for standard setups).
5. Click calculate – The tool instantly gives you V_out in volts.

You’ll also see a step-by-step explanation of the calculation. This helps beginners understand how the output is derived from inputs.
