NTE890
Integrated Circuit
Voltage to Frequency Converter
Description:
The NTE890 is an integrated circuit in an 8–Lead DIP type package and provides a simple method
of A/D conversion. It has all the inherent advantages of the voltage–to–frequency conversion tech-
nique. The output is a series of constant duration pulses. The frequency of the pulses is proportional
to the applied input voltage. This converter is designed for use in a wide range of data conversion
and remote sensing applications.
