General Description

The TC9400/TC9401/TC9402 are low cost voltage-to-

frequency (V/F) converters, utilizing low power CMOS

technology. The converters accept a variable analog

input signal and generate an output pulse train, whose

frequency is linearly proportional to the input voltage.

The devices can also be used as highly accurate fre-

quency-to-voltage (F/V) converters, accepting virtually

any input frequency waveform and providing a linearly

proportional voltage output.

A complete V/F or F/V system only requires the addi-

tion of two capacitors, three resistors, and reference

voltage.
