DESCRIPTION

· The LMx31 family of voltage-to-frequency converters is designed for simple, low-cost circuits.

· It is ideal for analog-to-digital conversion, precision frequency-to-voltage conversion, long-term integration, linear frequency modulation or demodulation, and other functions.

· The output is a pulse train with a frequency precisely proportional to the applied input voltage, offering inherent advantages of voltage-to-frequency conversion techniques.

FEATURES

· Ensured linearity with a maximum of 0.01%.

· Improved performance in existing voltage-to-frequency conversion applications.

· Operates on a single 5-V supply or split supply.

· Pulse output compatible with all logic forms.

· Excellent temperature stability: ±50ppm/°C maximum.

· Low power consumption: 15mW typical at 5V.

· Wide dynamic range, 100dB minimum at 10-kHz full-scale frequency.

· Wide range of full-scale frequency: 1Hz to 100kHz.

· Low-cost solution.

APPLICATIONS

· Voltage to frequency conversions.

· Frequency to voltage conversions.

· Remote-sensor monitoring.

· Tachometers.
