ADN4620BRSZ

Overview

The ADN4620BRSZ is a dual-channel digital isolator utilizing iCoupler technology, designed for LVDS signal transmission at data rates up to 2.5 Gbps. It features galvanic isolation with an insulation voltage of 3750 Vrms and a common-mode transient immunity of 35 kV/µs. The device operates within a supply voltage range of 1.7 V to 1.9 V for the A-side and 3 V to 3.6 V for the B-side, consuming 80 mA of operating current. It exhibits a propagation delay of 2.15 ns with rise and fall times of 180 ps. The component is housed in a 20-lead SSOP package and supports bidirectional or unidirectional configurations across two forward channels.

Feature Summary

• Integrates iCoupler technology for high-speed galvanic isolation without external magnetic components
• Supports low-voltage differential signaling (LVDS) protocols with very low jitter characteristics
• Provides robust common-mode transient immunity suitable for noisy industrial environments

Applications

• High-performance data communication systems requiring isolated LVDS interfaces
• Industrial automation networks utilizing isolated serial communication protocols
• Medical equipment requiring reinforced galvanic isolation for patient safety

Procurement Notes

Verify the specific suffix configuration against official Analog Devices documentation to ensure compatibility with required channel directionality and packaging options. Confirm that the SSOP-20 footprint matches the target PCB design constraints. Check current availability status as distribution may vary by region. Ensure compliance with RoHS directives relevant to the manufacturing date code.

Selection Notes

Select this component when designing systems requiring isolated LVDS buffers with high data throughput and low skew. Consider the 3750 Vrms insulation rating for safety-critical applications. Evaluate power consumption requirements given the 80 mA operating current. Ensure the 2.15 ns propagation delay meets system timing budgets. Verify thermal dissipation capabilities within the SSOP-20 package for the intended ambient temperature range.

Part Context

This part belongs to the ADN4620 series of dual-channel digital isolators from Analog Devices. It complements other variants like the ADN4621 which offers different channel configurations. The series leverages silicon dioxide-based iCoupler technology to provide compact, reliable isolation solutions for high-speed digital signals in demanding electronic environments.

Replacement Considerations

Direct substitutes include the ADN4621BRIZ-RL for bidirectional LVDS isolation needs. Alternative family members such as the ADN4652BRSZ-RL7 offer lower data rates but similar isolation ratings. Verify pinout compatibility and electrical specifications before substituting.
