The AD654JR from Analog Devices is a monolithic Voltage-to-Frequency (V/F) converter designed for cost-effective signal conversion. This component integrates an input amplifier, a precision oscillator system, and a high-current output stage, requiring minimal external components for operation.
Key electrical specifications include a full-scale frequency of up to 500 kHz and a linearity error of ±0.2%. It operates from a wide single supply voltage range of 5 V to 36 V, drawing only 2.0 mA of quiescent current. The device offers a high input impedance of 250 MΩ and low drift, making it suitable for direct interfacing with small signals from sources like thermocouples or strain gauges.
The AD654JR provides a square-wave output and can drive up to 12 TTL loads. Its overall temperature coefficient is typically -50 ppm/°C, excluding external components. The converter is packaged in an 8-lead SOIC package, suitable for surface mounting.
Applications for the AD654JR include analog-to-digital conversion, isolated signal transmission, frequency-to-voltage conversion, and phase-locked loops. Its versatility and low component count make it a practical choice for various industrial and instrumentation applications.
