VOLTAGE-TO-FREQUENCY CONVERTER

FEATURES

DESCRIPTION

● FULL-SCALE FREQUENCY SET BY

The VFC100 voltage-to-frequency converter is an

important advance in VFCs. The well-proven charge

balance technique is used; however, the critical reset

integration period is derived from an external clock

frequency. The external clock accurately sets an out-

put full-scale frequency, eliminating error and drift

from the external timing components required for

other VFCs. A precision input resistor is provided

which accurately sets a 10V full-scale input voltage.

In many applications the required accuracy can be

achieved without external adjustment.

SYSTEM CLOCK; NO CRITICAL

EXTERNAL COMPONENTS REQUIRED

● PRECISION 10V FULL-SCALE INPUT,

0.5% max GAIN ERROR

● ACCURATE 5V REFERENCE VOLTAGE

● EXCELLENT LINEARITY:

0.02% max at 100kHz FS

0.1% max at 1MHz FS

● VERY LOW GAIN DRIFT: 50ppm/°C

The open collector active-low output provides fast fall

time on the important leading edge of output pulses,

and interfaces easily with TTL and CMOS circuitry.

An output one-shot circuit is particularly useful to

provide optimum output pulse widths for optical cou-

plers and transformers to achieve voltage isolation. An

accurate 5V reference is also provided which is useful

for applications such as offsetting for bipolar input

voltages, exciting bridges and sensors, and autocali-

bration schemes.
