ADN4621BRSZ-RL

Overview

The ADN4621BRSZ-RL is a dual-channel digital isolator from Analog Devices, designed for high-speed LVDS signal transmission. It features a data rate of 2.5 Gb/s and provides 3750 Vrms isolation via capacitive coupling. The device operates with bidirectional polarity and supports supply voltages ranging from 1.7 V to 1.9 V on the input side and 3 V to 3.6 V on the output side. It exhibits a propagation delay of 2.15 ns and draws 65 mA of operating current. Housed in an SSOP-20 package, it functions within a temperature range of -40°C to +125°C.

Feature Summary

• Provides galvanic isolation between circuits using capacitive coupling technology.
• Supports bidirectional signal transmission for flexible interface configurations.
• Enables high-speed data transfer at rates up to 2.5 Gb/s.

Applications

• LVDS interface isolation

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status and specific packaging options such as reel or cut tape availability. Ensure the part number matches the exact suffix requirements for your assembly process. Check for any recent product change notifications that may affect specifications or sourcing.

Selection Notes

Select this component when bidirectional LVDS isolation is required at high data rates. Consider the SSOP-20 package constraints and the specific voltage domain requirements for both sides of the isolator. Evaluate the thermal performance given the operating current and ambient temperature range. Compare against magnetic coupling alternatives if lower power consumption is critical.

Part Context

This part belongs to the ADN4621 series of digital isolators. It shares the same core functionality as the ADN4621BRIZ-RL but differs in the package type, utilizing an SSOP-20 form factor instead of other available packages. It is distinct from the ADN4651 and ADN4652 series which utilize magnetic coupling and different data rates.
