Analog Devices Converters, Temperature Sensors and Signal Conditioners Voltage-to-Frequency/Frequency-to-Voltage Converters Voltage-to-Frequency Converters (VFCs) convert analog voltage or current levels to pulse trains or square waves in logic compatible form (usually TTL) at frequencies that are accurately proportional to the analog quantity. The output continuously tracks the input signal, responding directly to changes in the input signal. Frequency-to-Voltage Converters (FVCs) perform the inverse operation; they accept a wide variety of periodic waveforms and produce an analog output proportional to frequency. Combining adjustable threshold, gain and output offset with low linearity error, F/V converters offer economical solutions to a wide variety of applications where it is required to convert frequency to an analog voltage. Applications of both forms of conversion, as appropriate to specific device types, are illustrated with varying degrees of detail on the individual product datasheets.
