ADUM1301WTRWZ

Overview

The ADUM1301WTRWZ is a digital isolator from the Analog Devices ADUM1301 series, housed in a 16-pin SOIC package. It provides three channels of isolation with a unidirectional configuration (2 transmitters, 1 receiver). The device supports data rates up to 90 Mb/s and operates on a supply voltage range of 2.7 V to 5.5 V. Key electrical specifications include an insulation voltage of 2500 Vrms, a propagation delay of 32 ns, and a common-mode transient immunity of 25 kV/µs. It is qualified under AEC-Q100 standards for automotive applications and functions within a temperature range of -40°C to +125°C.

Feature Summary

• Utilizes iCoupler magnetic coupling technology for signal transmission across isolation barriers without external magnetics.
• Provides robust galvanic isolation with high common-mode transient immunity to protect sensitive circuitry.
• Features low power consumption suitable for battery-operated and energy-efficient systems.
• Includes integrated logic and timing compensation for precise pulse width distortion performance.

Applications

• Automotive electronic control units requiring isolated communication interfaces
• Industrial automation systems with noisy electrical environments
• Medical equipment needing patient isolation safety compliance
• Power electronics monitoring and gate drive circuits

Procurement Notes

Verify the specific suffix WTRWZ indicates the tube packaging format distinct from reel variants. Confirm AEC-Q100 qualification status if automotive grade certification is required for your bill of materials. Check current availability as distribution may be limited or restricted in certain regions. Ensure compatibility with existing PCB footprint designs for the 16-SOIC package before ordering.

Selection Notes

Select this component when three isolated channels are needed with unidirectional data flow. Compare against bidirectional variants like the ADUM1301WSRWZ-RL if reverse communication is required. Consider the 90 Mb/s speed limit against higher-speed alternatives if system requirements exceed this threshold. Evaluate power budget constraints against the specified operating current values for both sides of the isolator.

Part Context

This part belongs to the ADUM1301 family of iCoupler digital isolators. It shares architectural similarities with other members like the ADUM1300 but differs in channel count and directionality. The series represents Analog Devices' solid-core isolation technology, offering reliability advantages over traditional optocouplers in terms of lifetime and consistency.

Replacement Considerations

The ADUM1300WTRWZ is listed as a parameter-equivalent substitute. Verify functional differences such as channel configuration and directionality before swapping. Ensure pinout compatibility and thermal characteristics match the original design requirements.
