Additional Information
Monolithic Voltage to Frequency Converters
8 Pin Dip Package
The AD654 is a monolithic V/F converter consisting of an input amplifier, a precision oscillator system, and a high current output stage. The only requirement to set the desired full scale frequency and a selectable pull up resistor for the open collector out put stage is an RC timing network.
