Description
This voltage to frequency converter provides the output
pulse train at a frequency precisely proportional 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.
