ADUM1301CRWZ

Overview

The ADUM1301CRWZ 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 voltage with a common-mode transient immunity of 25 kV/µs. Key timing parameters include a propagation delay of 27 ns and rise/fall times of 3 ns. It functions in unidirectional mode across an operating temperature range of -40°C to +105°C.

Feature Summary

• Integrates three independent digital channels using monolithic transformer-based iCoupler technology for signal transmission.
• Provides robust electrical isolation with high common-mode transient immunity to protect sensitive circuitry.
• Supports high-speed data communication with low propagation delay and minimal pulse width distortion.

Applications

• Controller Area Network (CAN) bus isolation in industrial and automotive systems
• General-purpose digital isolation for microcontroller interfaces
• Isolation barriers in motor control applications

Procurement Notes

Verify the specific suffix 'CRWZ' against official Analog Devices documentation to confirm package type and temperature grade. Confirm availability status as distribution listings may indicate limited stock or discontinuation. Ensure the ordering part number matches the required reel or cut-tape configuration for your manufacturing process.

Selection Notes

Select this component when three isolated bidirectional or unidirectional channels are required in a compact SOIC-16 package. Compare performance metrics such as data rate and isolation voltage against other iCoupler variants like the ADUM1301ARWZ if lower speed or different packaging is acceptable. Verify that the 2500 Vrms rating meets the safety requirements of the target application.

Part Context
