Voltage-to-Frequency Converters
General Description
The LM131 LM231 LM331 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
voltage-to-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 conv...
