TC9400/9401/9402
Voltage-to-Frequency / Frequency-to-Voltage Converters
Features: General Description: VOLTAGE-TO-FREQUENCY The TC9400/9401/9402 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. Choice of Linearity:
-TC9401: 0.01%
-TC9400: 0.05%
-TC9402: 0.25% DC to 100 kHz (F/V) or 1 Hz to 100 kHz (V/F) Low Power Dissipation: 27 mW (Typ.) Single/Dual Supply Operation:
-+8V to +15V or В±4V to В±7.5V Gain Temperature Stability: В±25 ppm/В°C (Typ.) Programmable Scale Factor FREQUENCY-TO-VOLTAGE Operation: DC to 100 kHz Choice of Linearity:
-TC9401: 0.02%
-TC9400: 0.05%
-TC9402: 0.25% Programmable Scale Factor 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. Package Type
