VFC62 single voltage / frequency and frequency / voltage converter can easily convert analog signals into digital signals , digital pulse train repetition rate is proportional to the analog input voltage amplitude . As the noise suppression in digital form , analog signals can be transmitted long distances without compromising performance . It can be used to convert the binary counter to the microprocessor , can be converted back to analog form . Digital outputs with active pull type , open collector output than the average load greater drive capability . Output pulse level with DTL, TTL and CMOS logic family compatible . Typical application circuit as shown.
