ADN4656BRSZ-RL7

Overview

The ADN4656BRSZ-RL7 is a digital isolator from Analog Devices, featuring magnetic coupling technology. It provides dual isolation with one receiver and one transmitter channel, supporting LVDS signaling at data rates up to 1.25 Gb/s. The device operates within a supply voltage range of 2.375 V to 3.6 V and withstands an insulation voltage of 3750 Vrms. Key electrical parameters include a propagation delay of 4 ns, rise/fall times of 350 ps, and a power dissipation of 1.8 W. It functions in temperatures from -40°C to +125°C and is housed in a 20-SSOP package.

Feature Summary

• Utilizes magnetic coupling for high-speed signal transmission with low latency.
• Supports unidirectional data flow with integrated receive and transmit channels.
• Provides robust galvanic isolation suitable for high-voltage noise environments.

Applications

• LVDS Gigabit interface development
• High-speed digital isolation circuits
• Industrial communication systems

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm the specific suffix matches the required reel configuration. Check current availability status as supply may be limited. Ensure compliance with RoHS directives and humidity sensitivity handling requirements during storage and assembly processes.

Selection Notes

Select this component when LVDS compatibility and gigabit data rates are required. The 20-SSOP package suits surface-mount applications with space constraints. Consider the 3750 Vrms isolation rating for safety-critical designs. Evaluate the 4 ns propagation delay against system timing budgets.

Part Context

This part belongs to the ADN4656 series of digital isolators. It is designed for high-performance applications requiring reliable signal transfer across isolation barriers. The EVAL-ADN4656EB1Z evaluation board is available for testing and development purposes.

Replacement Considerations

Check for pin-compatible alternatives within the ADN465x family. Verify that substitute parts maintain the same LVDS interface and isolation voltage ratings before integration into existing designs.
