FEATURES  
DESCRIPTION  
HIGH LINEARITY: 12 to 14 bits  
±0.005% max at 10kHz FS  
±0.03% max at 100kHz FS  
±0.1% typ at 1MHz FS  
The VFC320 monolithic voltage-to-frequency and frequency-to-  
voltage converter provides a simple low cost method of convert-  
ing analog signals into digital pulses. The digital output is an  
open collector and the digital pulse train repetition rate is propor-  
tional to the amplitude of the analog input voltage. Output pulses  
are compatible with TTL, and CMOS logic families.  
V/F OR F/V CONVERSION  
6-DECADE DYNAMIC RANGE  
GAIN DRIFT: 20ppm/°C max  
OUTPUT TTL/CMOS COMPATIBLE  
High linearity (0.005%, max at 10kHz FS) is achieved with  
relatively few external components. Two external resistors and  
two external capacitors are required to operate. Full scale fre-  
quency and input voltage are determined by a resistor in series  
with –In and two capacitors (one-shot timing and input amplifier  
integration). The other resistor is a non-critical open collector  
pull-up (fOUT to +VCC). The VFC320 is available in two perfor-  
mance grades. The VFC320 is specified for the –25°C to +85°C,  
range.
