Selecting R2  
pin 10 should be biased closer to zero to insure that the input  
signal at pin 10 crosses the zero threshold.  
R2 = VPULLUP/(8mA – ILOAD  
)
Errors are nulled using 0.001 • full scale frequency to null  
offset, and full scale frequency to null the gain error. The  
procedure is given on this page. Use equations from V/F  
calculations to find R1, R3, R4, C1 and C2.  
=5V/(8mA – 1.6mA), one TTL-load = 1.6mA  
=781Ω  
Choose a 7501/4-watt carbon compensation resistor with  
±5% tolerance.  
TYPICAL APPLICATIONS  
FREQUENCY-TO-VOLTAGE CONVERSION  
To operate the VFC320 as a frequency-to-voltage converter,  
connect the unit as shown in Figure 9. To interface with  
TTL-logic, the input should be coupled through a capacitor,  
and the input to pin 10 biased near +2.5V. The converter will  
detect the falling edges of the input pulse train as the voltage  
at pin 10 crosses zero. Choose C3 to make t = 0.1t (see  
Figure 9). For input signals with amplitudes less than 5V,  
Excellent linearity, wide dynamic range, and compatible  
TTL, DTL, and CMOS digital output make the VFC320  
ideal for a variety of VFC applications. High accuracy  
allows the VFC320 to be used where absolute or exact  
readings must be made. It is also suitable for systems  
requiring high resolution up to 14 bits  
Figures 10-14 show typical applications of the VFC320.
