Overview
The ADUM7241ARZ-RL7 is a dual-channel digital isolator manufactured by Analog Devices Inc. It operates within a supply voltage range of 3 V to 5.5 V and supports data rates up to 1 Mb/s. The device provides an insulation voltage of 1000 Vrms and features a common-mode transient immunity (CMTI) of 15 kV/µs. It utilizes magnetic coupling technology for signal isolation and is housed in an 8-SOIC package with a width of 3.90 mm.
Feature Summary
- Provides galvanic isolation between circuits using magnetic coupling technology
- Supports bidirectional data transmission with high common-mode transient immunity
- Operates on a single power supply ranging from 3 V to 5.5 V
Applications
- General-purpose digital isolation in industrial systems
- Isolation for microcontroller interfaces
- Signal isolation in measurement and control applications
Procurement Notes
Verify the specific suffix RL7 indicates reel packaging when sourcing. Confirm current availability status as distribution channels may report limited stock or discontinuation. Ensure the SOIC-8 footprint matches the target PCB design. Validate RoHS compliance documentation for regulatory requirements.
Selection Notes
Select this component when 1000 Vrms isolation is sufficient for the application. Consider the 1 Mb/s data rate limit for high-speed communication needs. Evaluate the 15 kV/µs CMTI against noise environments. Compare power consumption against other isolators if low standby current is critical.
Part Context
This part belongs to the ADUM724x series of digital isolators. It shares the SOIC-8 package and magnetic coupling architecture with similar models like the ADUM7240. The series focuses on providing reliable isolation for general-purpose digital signals without requiring external transformers.
Replacement Considerations
Check for direct pin-compatible substitutes within the ADUM724x family. Verify that alternative parts meet the same 1000 Vrms insulation and 15 kV/µs CMTI specifications. Ensure the replacement supports the required 1 Mb/s data rate.
