ADN4650BRSZ-RL7

Overview

The ADN4650BRSZ-RL7 is a dual-channel digital isolator from Analog Devices, utilizing iCoupler magnetic coupling technology. It supports LVDS signaling with a maximum data rate of 600 Mbps and offers 3750 Vrms isolation voltage. The device features a typical propagation delay of 4 ns and operates within a supply voltage range of 2.375 V to 2.625 V. It is housed in a 20-SSOP package and functions bidirectionally or unidirectionally depending on configuration, with an operating temperature range of -40°C to +125°C.

Feature Summary

• Integrates two independent channels for high-speed signal transmission using proprietary magnetic coupling architecture.
• Provides robust electrical isolation rated at 3750 Vrms to protect sensitive circuitry across different ground potentials.
• Supports Low-Voltage Differential Signaling (LVDS) standards for reliable data integrity at speeds up to 600 Mbps.
• Delivers low propagation delay characteristics suitable for time-critical communication interfaces.

Applications

• Industrial automation systems requiring galvanic isolation between controllers and sensors.
• Medical equipment needing safe patient isolation and noise immunity.
• Power electronics monitoring circuits where high common-mode transient immunity is essential.
• Communication interface modules connecting microprocessors to peripheral devices.

Procurement Notes

Verify the specific suffix RL7 indicates reel packaging when sourcing. Confirm availability status as distribution channels may report limited stock or restricted supply conditions. Ensure compatibility with SSOP-20 footprint requirements during PCB layout. Check RoHS compliance documentation for regulatory adherence in target markets.

Selection Notes

Choose this component when dual-channel LVDS isolation is required with high data throughput. Consider the 3750 Vrms rating for applications demanding significant potential difference separation. Evaluate the 2.375 V to 2.625 V supply constraint against available power rails. Assess the 20-SSOP package size against board space limitations compared to wider SOIC options.

Part Context

This part belongs to the ADN4650 series of iCoupler digital isolators. It shares core specifications with variants like ADN4650BRWZ but differs in package type and shipping configuration. The series is designed for high-performance isolation needs in industrial and commercial environments.

Replacement Considerations

Direct substitutes include ADN4650BRWZ-RL7 which offers identical electrical performance in a WIDE package format. Verify pinout compatibility and thermal dissipation differences when swapping between SSOP and WIDE packages.
