Description

The TC9400/TC9401/TC9402 are low cost voltage-tofrequency (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 TC9400/TC9401/TC9402 devices can also be used as highly accurate frequency- 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 addition of two capacitors, three resistors, and reference voltage.
