NTE890 - NTE Electronics

NTE890 Integrated Circuit Voltage to Frequency Converter

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 technique. 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.
