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-propor-
tional voltage output.
A complete V/F or F/V system only requires the addition
of two capacitors, three resistors, and reference voltage.
