LM331 DIP-8 Voltage Frequency Converter Integrated

The LMx31 family of voltage-to-frequency converters is ideal for use in simple low-cost circuits for analog-to-digital conversion, precision frequency-to-voltage conversion, long-term integration, linear frequency modulation or demodulation. The output, when used as a voltage-to-frequency converter, is a train of pulses at a frequency exactly proportional to the applied input voltage. Therefore, it provides all the inherent advantages of voltage-to-frequency conversion techniques and is easy to implement in all standard voltage-to-frequency converter applications.
