ADUM1441ARSZ-RL7

Digital Isolators Overview

The ADUM1441ARSZ-RL7 is a micro-power quad-channel digital isolator utilizing Analog Devices iCoupler technology. It provides four independent isolation channels with unidirectional signal transmission. The device operates on a single 3V to 5.5V supply and supports data rates up to 2 Mbps. Key electrical specifications include a 3750 Vrms isolation voltage, a common-mode transient immunity of 25 kV/µs, and a maximum propagation delay of 25 ns. It is housed in a 20-lead SSOP package and functions within an operating temperature range of -40°C to 125°C.

Digital Isolators Feature Summary

Digital Isolators Procurement Notes

Verify the specific suffix ARSZ-RL7 against official Analog Devices documentation to confirm the 20-lead SSOP package and reel packaging configuration. Ensure compatibility with your PCB footprint and reflow soldering profiles. Cross-reference the datasheet revision date to validate current electrical parameters and pinout assignments before finalizing procurement orders.

Digital Isolators Selection Notes

Select this component when four isolated bidirectional or unidirectional channels are required in a compact form factor. It is suitable for applications demanding low power dissipation and high reliability. Compare its propagation delay and isolation voltage ratings against system requirements to ensure adequate performance margins for signal integrity and safety compliance.

Digital Isolators Part Context

This part belongs to the ADuM144x family of micro-power quad-channel digital isolators. These devices integrate analog and digital circuits on a monolithic CMOS substrate to create complete isolation solutions. The series is designed to replace traditional optocouplers while offering superior performance in speed, power, and size.

Digital Isolators Replacement Considerations

Official substitutes include other variants within the ADuM144x family, such as the ADUM1440 or ADUM1442, which share similar pinouts and functionality but may differ in channel directionality or specific electrical characteristics. Verify pin-to-pin compatibility and parameter equivalence before substitution.
