AD654JR-REEL

Overview

The AD654JR-REEL is a voltage-to-frequency and frequency-to-voltage converter manufactured by Analog Devices Inc. It operates within a temperature range of -40°C to +85°C and supports single or dual power supplies. The device features a full-scale frequency of 500 kHz and an integral nonlinearity (INL) of +/- 0.4% FSR. It is packaged in SOIC-8 format and distributed on a reel.

Feature Summary

• Performs bidirectional conversion between analog voltage signals and digital frequency outputs.
• Provides high linearity performance with specified integral nonlinearity characteristics.
• Supports flexible power supply configurations for diverse system requirements.

Applications

• Precision measurement systems requiring analog-to-digital interface via frequency
• Data acquisition circuits utilizing voltage-to-frequency modulation
• Frequency-to-voltage demodulation in signal processing chains

Procurement Notes

Verify component authenticity through authorized channels due to limited availability status. Confirm package integrity upon receipt as the item is supplied in reel packaging. Check for lead-free compliance markings if RoHS adherence is required for your specific application standards. Ensure storage conditions meet humidity sensitivity levels to prevent moisture damage prior to soldering.

Selection Notes

Select this component when a monolithic solution for V/F and F/V conversion is needed without external timing components. Consider the SOIC-8 surface mount package for automated assembly processes. Evaluate the +/- 0.4% INL specification against your system's accuracy requirements. Verify that the 500 kHz maximum frequency meets your bandwidth needs.

Part Context

This part belongs to the AD654 series of voltage-to-frequency converters from Analog Devices. It shares functional similarities with other variants like the AD654JRZ but differs in packaging and distribution format. The series is designed for cost-effective precision conversion tasks in industrial and scientific instrumentation applications.
