ADN4655BRWZ

Overview

The ADN4655BRWZ is a dual-channel digital isolator utilizing iCoupler magnetic coupling technology. It supports Low Voltage Differential Signaling (LVDS) with a data rate of 1.25 Gb/s and offers 5000 Vrms isolation voltage. The device features a 20-lead SOIC package, operates on a 2.375 V to 3.6 V supply, and provides a propagation delay of 4 ns with 350 ps rise/fall times.

Feature Summary

• Integrates two independent LVDS channels for high-speed bidirectional or unidirectional signal transmission across isolation barriers.
• Employs on-chip transformer-based magnetic coupling to provide robust electrical isolation without optical components.
• Designed for low jitter performance suitable for gigabit data rates in noise-sensitive environments.

Applications

• High-speed serial communication interfaces requiring galvanic isolation
• Industrial automation systems with noisy ground potentials
• Medical equipment requiring reinforced isolation standards

Procurement Notes

Verify the specific suffix BRWZ confirms the 20-SOIC package and 5000 Vrms rating. Confirm RoHS compliance status through official documentation. Check for moisture sensitivity level requirements during storage and handling. Ensure the supplier provides valid traceability for Analog Devices Inc. manufactured units.

Selection Notes

Select this component when 1.25 Gb/s LVDS throughput is required with 5000 Vrms isolation. Compare against ADN4654 variants if lower speed or different packaging is acceptable. Verify that the 20-lead SOIC footprint fits the target PCB layout constraints.

Part Context

Part of the ADN465x family of LVDS digital isolators from Analog Devices. Shares architectural similarities with ADN4654 and ADN4656 but differs in speed ratings and package options within the same iCoupler product line.

Replacement Considerations

ADN4655BRSZ serves as a direct pin-compatible alternative in SSOP-20 package with 3750 Vrms isolation. Verify package dimensions and isolation voltage ratings match system requirements before substitution.

FAQ

What is the maximum common-mode transient immunity?

The device specifies a common-mode transient immunity (CMTI) of 25 kV/µs.

Does the ADN4655BRWZ include a shutdown function?

No, the ADN4655BRWZ does not feature a dedicated shutdown pin; it operates continuously when powered.
