ADUM1301CRWZ-RL

Overview

The ADUM1301CRWZ-RL is a triple-channel digital isolator from Analog Devices, utilizing iCoupler magnetic coupling technology. It operates within a supply voltage range of 2.7 V to 5.5 V and supports data rates up to 120 Mb/s. The device provides 2500 Vrms isolation and features a common mode transient immunity of 25 kV/µs. It is housed in a 16-pin SOIC package with unidirectional channel configuration. Operating temperatures span from -40°C to +105°C, with propagation delays as low as 27 ns.

Feature Summary

• Triple-channel digital isolation using proprietary iCoupler magnetic coupling technology
• High common mode transient immunity for reliable signal transmission in noisy environments
• Unidirectional data flow capability across all three channels
• Wide operating temperature range suitable for industrial applications

Applications

• CAN bus isolation in industrial and automotive networks
• General purpose digital isolation for sensor interfaces
• Isolation barriers in motor control systems

Procurement Notes

Verify current availability status as the component may be subject to limited supply or factory special orders. Confirm RoHS compliance and moisture sensitivity level requirements against specific project standards. Ensure the reel packaging format aligns with automated assembly equipment capabilities before finalizing procurement plans.

Selection Notes

Select this component when high-speed data transmission up to 120 Mb/s is required alongside robust galvanic isolation. The unidirectional nature suits applications where signal flow is strictly one-way. Consider the 16-SOIC package dimensions for PCB layout constraints and verify that the 2500 Vrms isolation rating meets safety standards for the intended electrical environment.

Part Context

This part belongs to the ADUM1301 series of triple-channel digital isolators. It shares architectural similarities with other iCoupler devices but is distinguished by its specific speed and isolation ratings. The suffix indicates reel packaging, differentiating it from tube-packaged variants like the ADUM1301ARWZ.

Replacement Considerations

The ADUM1301ARWZ-RL is a confirmed substitute variant within the same family. Verify pin compatibility and ensure the alternative meets the specific data rate and isolation voltage requirements of the design.
