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.
