AD654JR-REEL7

Overview

The AD654JR-REEL7 is a voltage-to-frequency and frequency-to-voltage converter manufactured by Analog Devices Inc. It operates within a full-scale frequency range of 500 kHz and exhibits an integral nonlinearity (INL) of +/- 0.4% FSR. The device supports both single and dual power supply configurations, with an operating temperature range spanning from -40°C to +85°C. It is supplied in reel packaging.

Feature Summary

• Performs bidirectional conversion between analog voltage signals and digital frequency outputs.
• Provides high linearity performance suitable for precision measurement applications.

Applications

• Voltage-to-frequency conversion circuits
• Frequency-to-voltage conversion circuits

Procurement Notes

Verify current availability status as the component may be subject to limited supply or factory special order conditions. Confirm that the REEL7 suffix corresponds to the required tape and reel packaging format for your assembly process. Ensure compatibility with single or dual power supply designs based on specific system requirements.

Selection Notes

Select this component when a low-cost V/F converter with moderate accuracy is required. The +/- 0.4% INL specification suits general-purpose applications where extreme precision is not critical. Consider the SOIC-8 surface mount package for PCB layout constraints and verify thermal management needs within the specified industrial temperature range.

Part Context

This part belongs to the AD654 series of voltage-frequency converters. It serves as a simplified design basis for similar conversion applications alongside other members like the AD537, AD650, and AD651. The series is designed for straightforward implementation in data acquisition systems requiring signal digitization via frequency modulation.
