VFC/FVC 100kHz 14-Pin SOIC N T/R

The TC9400 is 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 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.
