AD654JRZ

Overview

The AD654JRZ is a voltage-to-frequency and frequency-to-voltage converter manufactured by Analog Devices Inc. It operates on dual power supplies within a minimum voltage of 4.5 V and a maximum of 36 V. The device supports a full-scale frequency of 500 kHz with an integral nonlinearity of +/- 0.4% FSR. It functions in temperatures ranging from -40 C to +85 C and is housed in an SOIC-8 surface-mount package.

Feature Summary

• Performs bidirectional conversion between analog voltage signals and digital frequency outputs.
• Provides high linearity performance suitable for precision measurement applications.
• Operates reliably across extended industrial temperature ranges.

Applications

• Industrial process control systems requiring precise signal conditioning
• Data acquisition modules for sensor interface
• Frequency modulation circuits

Procurement Notes

Verify current availability status directly with authorized distributors, as supply may be limited or subject to factory special orders. Confirm RoHS compliance details and specific packaging options such as tube or reel configurations before finalizing procurement plans.

Selection Notes

Select this component when dual-supply operation is available and surface-mount integration is required. Ensure the application demands a full-scale frequency capability of 500 kHz and can accommodate the specified integral nonlinearity characteristics for accurate signal processing.

Part Context

This part belongs to the AD654 series of data converter ICs designed for cost-effective V/F and F/V conversion tasks. It serves as a bridge between analog sensing elements and digital processing units, enabling accurate transmission of analog information over long distances using frequency-based signaling methods.

Replacement Considerations

Consult official documentation for verified substitute part numbers. Cross-reference pinouts and electrical specifications carefully to ensure compatibility with existing circuit designs.
