ADUM5211BRSZ-RL7

Overview

The ADUM5211BRSZ-RL7 is a dual-channel digital isolator from Analog Devices, featuring an integrated DC-to-DC converter. It provides bidirectional data isolation with unidirectional polarity across two channels. The device operates within a supply voltage range of 3.135 V to 5.5 V and supports a data rate of 100 Mb/s. It offers an insulation voltage of 2500 Vrms using magnetic coupling technology. Key electrical parameters include a propagation delay of 15 ns, typical rise/fall times of 3 ns, and a pulse width of 1000 ns. Operating currents are specified at 4.7 mA and 4.9 mA. The component functions reliably between -40°C and +105°C and is housed in a 20-SSOP package.

Feature Summary

• Integrates a high-efficiency DC-to-DC converter for isolated power delivery alongside signal isolation
• Provides robust magnetic coupling isolation with high common-mode transient immunity
• Supports high-speed data transmission rates suitable for demanding industrial interfaces

Applications

• Industrial automation systems requiring galvanic isolation
• Medical equipment needing reliable signal and power separation
• Inverter motor control applications with isolated gate drives

Procurement Notes

Verify the specific suffix RL7 indicates reel packaging when ordering. Confirm the BRSZ designation corresponds to the SSOP-20 package variant. Ensure compatibility with the EVAL-ADUM5211EBZ development board if prototyping. Check RoHS compliance status through official manufacturer documentation before final procurement decisions.

Selection Notes

Select this component when both signal isolation and isolated power generation are required in a single package. The integrated DC/DC converter simplifies design by eliminating external magnetics. Consider the 100 Mb/s data rate and 15 ns latency for high-speed communication needs. Verify that the SSOP-20 footprint fits the target PCB layout constraints.

Part Context

This part belongs to the ADuM5211 family of dual-channel isolators with integrated power converters. It is designed to replace discrete solutions combining isolators and DC/DC converters. The series emphasizes space savings and reduced bill-of-materials complexity for isolated interface designs.
