ADUM1301WTRWZ53

Overview

The ADUM1301WTRWZ53 is a triple-channel digital isolator utilizing iCoupler technology. It operates within a supply voltage range of 2.7 V to 5.5 V and supports data rates up to 10 Mbps. The device provides 2500 Vrms isolation voltage with a minimum common-mode transient immunity (CMTI) of 25 kV/µs. Propagation delay is typically 32 ns, with pulse width distortion limited to 3 ns. It features a unidirectional channel configuration (2 Tx / 1 Rx) and functions across an operating temperature range of -40°C to +125°C.

Feature Summary

• Triple-channel magnetic coupling isolation architecture
• High common-mode transient immunity for noisy environments
• Wide operating temperature range suitable for industrial applications

Applications

• Industrial process control systems
• Medical equipment signal isolation
• Power metering interfaces

Procurement Notes

Verify the specific suffix '53' against official Analog Devices documentation to confirm package type and tape-and-reel specifications. Ensure compatibility with existing PCB footprints for the 16-SOIC form factor. Confirm that the unidirectional channel configuration meets system design requirements before procurement.

Selection Notes

Select this component when high-speed data transmission requires robust galvanic isolation in space-constrained designs. The wide temperature range and high CMTI make it suitable for electrically noisy industrial settings. Verify that the 2.7 V to 5.5 V supply range aligns with the logic levels of both sides of the isolation barrier.

Part Context

This part belongs to the ADuM130x series of triple-channel digital isolators from Analog Devices. It leverages iCoupler technology to provide isolation without external transformers or capacitors. The series is designed for general-purpose applications requiring reliable signal transmission across isolation barriers.

Replacement Considerations

Check for direct substitutes such as ADUM1301ARWZ-RL or ADUM1301WTRWZ. Verify pinout compatibility and electrical parameter equivalence before substitution.
