The converters accept a variable analog input signal and generate an output pulse train whose frequency is linearly proportional to the input voltage. The devices can also be used as highly-accurate fre- quency-to-voltage (F/V) converters, accepting virtually any input frequency waveform and providing a linearly-propor- tional voltage output. A complete V/F or F/V system only requires the addition of two capacitors, three resistors, and reference voltage.
