SNOSBI2C – JUNE 1999 – REVISED SEPTEMBER 2015 LMx31x Precision Voltage-to-Frequency Converters
1 Features 3 Description The LMx31 family of voltage-to-frequency converters
are ideally suited for use in simple low-cost circuits
for analog-to-digital conversion, precision frequencyto-voltage conversion, long-term integration, linear
frequency modulation or demodulation, and many
other functions. The output when used as a voltageto-frequency converter is a pulse train at a frequency
precisely proportional to the applied input voltage.
Thus, it provides all the inherent advantages of the
voltage-to-frequency conversion techniques, and is
easy to apply in all standard voltage-to-frequency
converter applications. 1 Ensured Linearity 0.01% Maximum
