ADUM6211BRSZ-RL7

Overview

The ADUM6211BRSZ-RL7 is a dual-channel digital isolator from Analog Devices, featuring an integrated DC/DC converter for power delivery across the isolation barrier. It operates with unidirectional signal paths at data rates up to 100 Mb/s and provides an insulation voltage of 3750 Vrms via magnetic coupling technology. The device functions within a supply voltage range of 3.15 V to 5.5 V, exhibiting a propagation delay of 15 ns. It is housed in an SSOP-20 package and supports operating temperatures from -40°C to +105°C.

Feature Summary

• Integrates a high-voltage DC/DC converter to provide isolated power without external components
• Utilizes on-chip coil technology for robust magnetic coupling isolation
• Supports high-speed data transmission with low propagation delay

Applications

• Industrial automation systems requiring galvanic isolation
• Medical equipment needing reinforced safety isolation
• Power metering applications with isolated communication interfaces

Procurement Notes

Verify component authenticity through authorized Analog Devices distributors or certified partners. Confirm the specific suffix RL7 matches the reel packaging requirement for your assembly line. Check current availability status as supply may be limited. Ensure storage conditions comply with moisture sensitivity levels specified in the datasheet prior to reflow soldering.

Selection Notes

Select this component when both signal isolation and isolated power delivery are required in a single package. It is suitable for designs needing high common-mode transient immunity and low skew between channels. Consider the SSOP-20 footprint constraints and thermal dissipation capabilities during PCB layout planning.

Part Context

This part belongs to the ADUM6211 series of digital isolators. It shares architectural similarities with other ADUM devices but is distinct due to its integrated power conversion capability. The series is designed to replace traditional optocouplers and transformer-based solutions in modern electronic systems.

Replacement Considerations

Direct replacements include ADUM6211ARSZ for tube packaging variants. Evaluate ADUM6212 if bidirectional channel support is required instead of unidirectional. Verify pin compatibility and electrical specifications before substituting with other analog devices.
