ADUM1246ARZ-RL7

Overview

The ADUM1246ARZ-RL7 is a dual-channel digital isolator from Analog Devices, utilizing iCoupler magnetic coupling technology. It operates within a supply voltage range of 2.25 V to 3.6 V and supports data rates up to 2 Mbps. The device provides 3750 Vrms isolation voltage and exhibits a common-mode transient immunity of 25 kV/µs. Key timing parameters include a maximum propagation delay of 180 ns and typical rise/fall times of 2 ns. It functions reliably across an operating temperature range of -40°C to +125°C and is housed in an 8-SOIC package.

Feature Summary

• Implements iCoupler magnetic coupling technology for galvanic isolation without external transformers.
• Supports bidirectional communication with independent input and output channels.
• Features high common-mode transient immunity to maintain signal integrity in noisy environments.
• Operates at ultralow power consumption suitable for energy-efficient designs.

Applications

• Industrial automation systems requiring isolated sensor interfaces
• Medical equipment needing patient isolation barriers
• Power metering applications involving high-voltage side monitoring

Procurement Notes

Verify the specific suffix RL7 indicates reel packaging when sourcing. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure the 8-SOIC footprint matches your PCB layout constraints. Check for any regional distribution restrictions that may affect availability. Validate that the 3.6 V maximum supply voltage aligns with your system logic levels.

Selection Notes

Select this component when bidirectional data transfer is required across an isolation barrier. It is appropriate for applications demanding low power consumption alongside moderate data speeds. Consider the 3750 Vrms isolation rating for safety-critical designs. Ensure the 8-SOIC package size fits within your spatial limitations. Verify compatibility with your system's voltage domain requirements.

Part Context

This part belongs to the ADUM124x series of general-purpose digital isolators. It shares the iCoupler architecture with other members like the ADUM1241 and ADUM1245. The series is designed for cost-effective isolation solutions in industrial and consumer markets. It complements Analog Devices' broader portfolio of interface and power management ICs.

Replacement Considerations

The ADUM1241ARZ-RL7 is a unidirectional alternative within the same family. The ADUM1245ARZ-RL7 offers similar specifications with potential pinout variations. Verify functional equivalence regarding channel directionality and isolation ratings before substitution.
