Low-Cost Voltage-to-Frequency Converter Chip

AD654 Is Easy to Use, Features Low-Power 5-Volt Operation; Operates with Full-Scale Frequencies Up to 500 kHz

The AD654JN is a monolithic V/F converter, packaged in an 8-pin plastic mini-DIP. Capable of operating on a single 5-volt supply, and drawing 2.5-mA maximum quiescent current, it requires only three external components—a resistor and a capacitor to set the frequency scale (for frequencies up to 500kHz), and an external pullup resistor to set the current from the open-collector output stage. Read full article
