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.
