TC9400/9401/9402

Voltage-to-Frequency/Frequency-to-Voltage Converters

Features

General Description

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.

VOLTAGE-TO-FREQUENCY

• Choice of Linearity

- TC9401: 0.01%

- TC9400: 0.05%

The devices can also be used as highly accurate fre-

quency-to-voltage (F/V) converters, accepting virtually

any input frequency waveform and providing a linearly

proportional voltage output.

- TC9402: 0.25%

• DC to 100kHz (F/V) or 1Hz to 100kHz (V/F)

• Low Power Dissipation: 27mW (Typ.)

• Single/Dual Supply Operation

- +8V to +15V or ±4V to ±7.5V

• Gain Temperature Stability: ±25 ppm/°C (Typ.)

• Programmable Scale Factor

A complete V/F or F/V system only requires the addi-

tion of two capacitors, three resistors, and reference

voltage.
