Product Summary

The VFC320SM is a voltage-to-frequency and frequency-to-voltage converter. It provides a simple low cost method of converting analog signals into digital pulses. The digital output of the VFC320SM is an open collector and the digital pulse train repetition rate is proportional to the amplitude of the analog input voltage. Output pulses are compatible with TTL, and CMOS logic families. The applications of the VFC320SM include: (1)inexpensive a/d and d/a converter; (2)digital panel meters; (3)two-wire digital transmission with noise immunity; (4)fm mod/demod of transducer signals; (5)precision long term integrator; (6)high resolution optical link for isolation; (7)ac line frequency monitor; (8)motor speed monitor and control.

Parametrics

VFC320SM absolute maximum ratings: (1)Supply Voltage: ±20V; (2)Output Sink Current at fOUT: 50mA; (3)Output Current at VOUT: +20mA; (4)Input Voltage, –Input: ±VCC; (5)Input Voltage, +Input: ±VCC; (6)Storage Temperature Range: –65℃ to +150℃; (7)Lead Temperature (soldering, 10s): +300℃.

Features

VFC320SM features: (1)high linearity, 12 to 14 bits: ±0.005% max at 10khz fs, ±0.03% max at 100khz fs, ±0.1% typ at 1mhz fs; (2)v/f or f/v conversion; (3)6-decade dynamic range; (4)20ppm/℃ max gain drift; (5)output ttl/cmos compatible.
