应用功能： V-F Converter This voltage to frequency converter provides the output pulse train at a frequencypreciselyproportional to the applied input voltage. The LM331 can operate at power supplies as low as 4.0V and be changed output frequency from 1Hz to 100KHz. It is ideally suited for use in simple low cost circuit for analog-to digital conversion, long term integration, linear frequency modulation or demodulation,frequency to voltage conversion, and many other functions.
