VOLTAGE-TO-FREQUENCY/FREQUENCY-TO-VOLTAGECONVERTERS

FEATURES

GENERAL DESCRIPTION

Voltage-to-Frequency

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 fre-

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

input frequency waveform and providing a linearly-propor-

tional voltage output.

■ Choice of Guaranteed Linearity:

TC9401.........................................................0.01%

TC9400.........................................................0.05%

TC9402.........................................................0.25%

■ DC to 100 kHz (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

A complete V/F or F/V system only requires the addition

of two capacitors, three resistors, and reference voltage.

■ Gain Temperature Stability .......... ± 25 ppm/°C Typ

■ Programmable Scale Factor
