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.
