ADN4620BRSZ-RL

Overview

The ADN4620BRSZ-RL is a dual-channel LVDS digital isolator manufactured by Analog Devices Inc. It provides galvanic isolation up to 3750Vrms between two isolated circuits. The device supports data rates of 2.5 Gbps with a propagation delay of 2.15 ns. It operates on supply voltages ranging from 1.7 V to 1.9 V and 3 V to 3.6 V, consuming 80 mA of operating current. Packaged in SSOP-20, it features a common mode transient immunity of 35 kV/µs and functions within a temperature range of -40°C to +125°C.

Feature Summary

• Dual-channel LVDS interface for high-speed data transmission
• Galvanic isolation capability up to 3750Vrms
• High common mode transient immunity of 35 kV/µs
• Low propagation delay for precise timing applications

Applications

• Industrial automation systems requiring robust signal isolation
• Medical equipment needing safe patient isolation barriers
• Power electronics control interfaces
• Data acquisition systems with ground potential differences

Procurement Notes

Verify the specific suffix RL indicates reel packaging when ordering. Confirm that the 3750Vrms isolation rating meets system safety requirements. Ensure supply voltage compatibility with both 1.8V and 3.3V logic domains. Check lead times due to potential limited availability status.

Selection Notes

Select this component for applications requiring bidirectional or unidirectional LVDS signaling across isolation barriers. Consider the SSOP-20 package size for space-constrained designs. Evaluate the 80 mA power consumption against thermal constraints. Compare CMTI specifications against noise environments in industrial settings.

Part Context

This part belongs to the ADN4620 series of digital isolators. It complements other variants like the ADN4624 which offers quad channels. The series utilizes capacitive coupling technology for isolation. Development tools such as EVAL-ADN4620EBZ are available for evaluation.

Replacement Considerations

Consider ADN4620BRSZ for tube packaging instead of reel. ADN4652BRSZ-RL offers lower speed at 600Mbps but similar channel count. Verify pinout compatibility before substitution.
