TC9400COD, Voltage-to-Frequency Converter, Voltage, 100kHz 0.05 %FSR @ 10 kHz, 14-Pin SOIC
- RS Stock No. 177-9688
- Mfr. Part No. TC9400COD
- Manufacturer Microchip
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 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.
