ADUM1286WARZ-RL7

Overview

The ADUM1286WARZ-RL7 is a dual-channel digital isolator from Analog Devices, utilizing magnetic coupling technology for signal transmission. It features bidirectional data channels with a maximum data rate of 100 Mb/s and an insulation voltage rating of 3000 Vrms. The device operates within a supply voltage range of 3.135 V to 5.5 V, consuming approximately 15 mA of working power current per channel. It exhibits a propagation delay of 50 ns and supports an operating temperature range from -40°C to +125°C. Packaged in an SOIC-8 surface-mount format, it holds AEC-Q100 qualification.

Feature Summary

• Implements magnetic coupling isolation for robust signal integrity across high-voltage barriers
• Provides bidirectional data transmission capability on two independent channels
• Supports high-speed communication with a data rate up to 100 Mb/s
• Certified for automotive applications through AEC-Q100 qualification standards

Applications

• Automotive electronic control units requiring isolated communication interfaces
• Industrial automation systems needing reliable galvanic isolation
• Medical equipment demanding high safety isolation standards
• Power electronics gate drive circuits requiring signal separation

Procurement Notes

Verify the specific suffix RL7 indicates reel packaging when sourcing. Confirm availability status as supply may be limited or subject to factory special orders. Ensure the SOIC-8 package variant matches the design footprint requirements. Cross-reference the AEC-Q100 qualification if automotive compliance is mandatory for the application.

Selection Notes

Select this component for applications requiring bidirectional isolation at speeds up to 100 Mb/s. Consider the 3000 Vrms insulation rating for high-noise environments. Evaluate the 15 mA power consumption against system energy constraints. Verify that the SOIC-8 package dimensions fit the PCB layout. Check thermal performance within the specified -40°C to +125°C operating range.

Part Context

This part belongs to the ADUM1286 series of small, low-power digital isolators. It shares the same core isolation architecture and pinout compatibility with other variants in the family, such as the ADUM1286ARZ and ADUM1286WBRZ. These devices are designed to replace bulky optocouplers while offering superior performance in speed, power, and size.

Replacement Considerations

Direct substitutes include ADUM1286ARZ and ADUM1286WBRZ. Verify functional equivalence regarding data rate and directionality before substitution. Ensure package compatibility and electrical parameter alignment.
