Voltage-to-Frequency & Frequency-to-Voltage Converters

Voltage to Frequency Converters and frequency to voltage converters are electrical devices that can you can use to change the frequency and voltage of a power source.

A VFC (voltage to frequency converter) is an oscillator with a frequency that is linearly proportional to a control voltage and consumes a very small amount of power.

An FVC (frequency to voltage converter) is an electronic device that converts current signal inputs to corresponding voltage outputs. They use analogue and digital channels.

What are voltage to frequency converters and frequency to voltage converters used for?

Voltage to frequency converters are typical components in analogue-to-digital conversion applications of engines, telecommunication devices and automotive components.

Frequency to voltage converters are suitable for speed governors, tachometers, timers, encoders and switches.

Types of voltage to frequency converters and frequency to voltage converters

VFCs come with either single or integrated circuit adaptations. Single circuit converters consist of analogue voltage amplifiers, oscillator circuits, resistors, capacitors and driving power supplies.

FVCs have integral, low pass or programmable filtering capabilities. Integral filters allow some signal input frequencies through but bar others. Low pass filters have a set threshold. Signals below the threshold are allowed to pass, while signals above are blocked.
