NJM4151 V-F / F-V CONVERTOR GENERAL DESCRIPTION PACKAGE OUTLINE The NJM4151 provide a simple low-cost method of A/D conversion. They have all the inherent advantages of the voltage-to-frequency conversion technique. The Output of NJM4151 is a series of pulses of constant duration. The frequency of the pulses is proportional to the applied input voltage. These converters are designed for use in a wide range of data conversion and remote sensing applications.
