ADUM220N1BRWZ-RL

Overview

The ADUM220N1BRWZ-RL is a dual-channel digital isolator from Analog Devices, utilizing magnetic coupling technology to provide electrical isolation between circuits. It operates within a supply voltage range of 2.7 V to 5.5 V and supports data rates up to 150 Mb/s. The device offers a rated insulation voltage of 5000 Vrms and a minimum common-mode transient immunity (CMTI) of 75 kV/µs. Packaged in a 16-pin SOIC with an 8.9 mm wide body, it functions across an industrial temperature range of -40°C to +125°C.

Feature Summary

• Provides robust galvanic isolation via magnetic coupling technology for signal integrity
• Features high common-mode transient immunity to withstand rapid voltage changes
• Supports bidirectional data transmission with independent input and output channels

Applications

• Industrial automation systems requiring isolated communication interfaces
• Medical equipment needing patient isolation barriers
• Power electronics monitoring and control circuits

Procurement Notes

Verify the specific suffix 'RL' indicates tape-and-reel packaging when sourcing. Confirm the operating temperature grade matches application requirements. Ensure the 16-SOIC footprint aligns with PCB layout constraints. Check for RoHS compliance status as per current manufacturing standards. Validate that the 5000 Vrms isolation rating meets safety regulatory needs for the target environment.

Selection Notes

Select this component when dual-channel isolation with high CMTI is required. Compare against single-channel variants if only one path is needed. Consider the 150 Mb/s speed limit for high-frequency applications. Evaluate power consumption at the intended supply voltage. Ensure the SOIC package width fits within available board space.

Part Context

This part belongs to the ADuM220x family of general-purpose digital isolators. It shares architectural similarities with other members like the ADUM2201 but differs in channel count and specific performance metrics. The family utilizes capacitive or magnetic coupling depending on the series, with this model employing magnetic techniques for enhanced noise rejection.

Replacement Considerations

The ADUM220N0BRWZ-RL is a parameter-equivalent alternative within the same series. Verify pinout compatibility before substitution. Check if the replacement meets the same CMTI and insulation voltage specifications.
