Texas Instruments LM331
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.| Part No. | LM331 |
