TC9402CPD Applications:

• Microprocessor Data Acquisition • 13-bit Analog-to-Digital Converters (ADC) • Analog Data Transmission and Recording • Phase Locked Loops • Frequency Meters/Tachometer • Motor Control • FM DemodulationThe TC9400/9401/9402 are low-cost Voltage-to-Fre-quency (V/F) converters, utilizing low-power CMOStechnology. The converters accept a variable analoginput signal and generate an output pulse train, whosefrequency is linearly proportional to the input voltage.The devices can also be used as highly accurateFrequency-to-Voltage(F/V) converters, acceptingvirtually any input frequency waveform and providing alinearly proportional voltage output.A complete V/F or F/V system only requires theaddition of two capacitors, three resistors, and refer-ence voltage.
