ADUM1301WSRWZ-RL

Overview

The ADUM1301WSRWZ-RL is a three-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 provides an isolation voltage of 2500 Vrms. The device supports data rates up to 90 Mb/s with a propagation delay of 100 ns. It features unidirectional signal transmission across three channels, configured as two transmitters and one receiver. The component is housed in a 16-pin SOIC package and is qualified under AEC-Q100 standards for automotive applications.

Feature Summary

• Integrates three independent digital isolation channels using proprietary magnetic coupling technology for high-speed signal transmission.
• Provides robust electrical isolation with a rated insulation voltage of 2500 Vrms to protect low-voltage circuits from high-voltage interference.
• Features unidirectional channel configuration optimized for specific transmitter and receiver roles within isolated systems.
• Includes internal circuitry to ensure stable operation across wide temperature ranges without requiring external components.

Applications

• Automotive electronic control units requiring AEC-Q100 qualified isolation
• Industrial communication bus interfaces such as CAN and LIN
• Medical equipment signal isolation for patient safety compliance

Procurement Notes

Verify the complete part number including the suffix to confirm the specific tape and reel packaging configuration. Ensure compatibility with moisture sensitivity levels during storage and handling. Confirm that the supplier provides valid traceability documentation for automotive-grade components. Check for any recent product change notices regarding pinout or electrical specifications before finalizing procurement orders.

Selection Notes

Select this component when three isolated bidirectional or unidirectional channels are required in a compact surface-mount package. Consider the 90 Mb/s data rate limit for high-speed interface applications. Evaluate the 2500 Vrms isolation rating against system safety requirements. Verify power consumption constraints given the specified operating current values for both logic sides.

Part Context

This device belongs to the ADUM1301 series of iCoupler digital isolators. It represents a class of magnetic isolation products designed to replace traditional optocouplers in modern electronic designs. The series offers improved performance characteristics including lower power consumption and higher reliability compared to legacy isolation technologies.

Replacement Considerations

Cross-reference with other ADUM1301 variants for different packaging options. Verify functional equivalence with competitor parts offering similar channel counts and isolation ratings. Ensure substitute components meet the same AEC-Q100 qualification standards if used in automotive applications.
