ADUM5241ARZ-RL7

Overview

The ADUM5241ARZ-RL7 is a dual-channel digital isolator from Analog Devices featuring an integrated isoPower DC-to-DC converter. It provides signal isolation up to 1 Mbps and delivers a regulated 5 V/10 mA isolated output with 50 mW power capability. The device operates within a supply voltage range of 2.7 V to 5.5 V, drawing 2.7 mA typical operating current. It offers high common-mode transient immunity of 35 kV/µs and supports unidirectional data flow. Packaged in a narrow-body 8-lead SOIC, it functions reliably between -40°C and +105°C.

Feature Summary

• Integrates an isolated DC-to-DC converter providing regulated 5 V/10 mA output for powering isolated side circuits
• Provides dual-channel digital signal isolation with 1 Mbps data rate capability
• Features high common-mode transient immunity for robust noise rejection in electrically noisy environments

Applications

• Industrial automation systems requiring galvanic isolation
• Medical equipment needing safe patient isolation barriers
• Automotive electronics utilizing magnetic coupling isolation

Procurement Notes

Verify the complete part number including the suffix RL7 to ensure correct reel packaging configuration. Confirm that the specific variant matches your system's voltage and channel directionality requirements. Check official Analog Devices documentation for RoHS compliance status and lead-free manufacturing details before finalizing procurement orders.

Selection Notes

Select this component when both signal isolation and isolated power generation are required in a single package. The integrated DC-DC converter eliminates the need for external isolated power supplies, simplifying board layout. Ensure the 50 mW output power meets the load requirements of the isolated side circuitry during design validation.

Part Context

This component belongs to the ADuM524x family of digital isolators. These devices combine analog and RF components on a monolithic CMOS substrate to provide reliable isolation using proprietary iCoupler technology. The family includes variants with different channel directions and power outputs, sharing the same narrow-body 8-lead SOIC footprint for design flexibility.

Replacement Considerations

Direct substitutes include ADUM5240ARZ-RL7 and ADUM5242ARZ-RL7. Verify channel directionality differences: ADUM5240 supports bidirectional channels, while ADUM5242 allows independent control of each channel's direction. Ensure pin compatibility and electrical specifications match the original design constraints.
