ADUM1201WTRZ-RL7

Overview

The ADUM1201WTRZ-RL7 is a dual-channel digital isolator from the ADUM1201 series, manufactured by Analog Devices Inc. It utilizes magnetic coupling technology to provide electrical isolation between circuits. The device features two unidirectional channels with a data rate of 25 Mb/s and an insulation voltage of 2500 Vrms. It operates within a supply voltage range of 2.7 V to 5.5 V and has a typical operating supply current of 6.3 mA. The propagation delay is specified at 150 ns, and it supports an extended operating temperature range from -40°C to +125°C. The component is AEC-Q100 qualified for automotive applications and is housed in an 8-SOIC package.

Feature Summary

• Provides galvanic isolation using iCoupler magnetic coupling technology
• Features high common-mode transient immunity of 25 kV/µs
• Supports unidirectional signal transmission across two isolated channels
• Qualified for automotive applications under AEC-Q100 standards

Applications

• Automotive electronic control units requiring isolated communication
• Industrial automation systems with noisy environments
• Medical equipment needing patient isolation barriers
• Power electronics monitoring and control interfaces

Procurement Notes

Verify the specific suffix RL7 indicates reel packaging when sourcing. Confirm the manufacturer part number matches ADUM1201WTRZ-RL7 exactly, as variations exist in channel count or speed ratings within the family. Check for AEC-Q100 certification if automotive grade is required. Ensure the SOIC-8 package width matches design constraints. Validate RoHS compliance status through official documentation before procurement.

Selection Notes

Select this component when bidirectional isolation is not required, as it offers only unidirectional channels. Compare against ADUM1200 variants if bidirectional functionality is needed. Consider the 25 Mb/s data rate limit for high-speed applications. Verify that the 2500 Vrms isolation rating meets system safety requirements. Evaluate power consumption against battery-operated constraints given the 6.3 mA supply current.

Part Context

This part belongs to the ADUM1201 series of dual-channel digital isolators. It shares the same core architecture as the ADUM1200 but differs in channel configuration and directionality. The WTRZ suffix denotes the wide temperature range and tape-and-reel packaging format. It is part of Analog Devices' iCoupler product line, which integrates isolation technology directly into silicon.

Replacement Considerations

ADUM1201WSRZ-RL7 is a direct substitute with identical specifications and packaging.
