ADUM1200WTRZ55

Overview

The ADUM1200WTRZ55 is a dual-channel digital isolator utilizing iCoupler technology, featuring 2/0 channel directionality. It operates within a 3V to 5.5V supply range and supports data rates up to 25Mbps. The device provides 2500Vrms isolation voltage and a minimum common-mode transient immunity of 25kV/µs. It is housed in an 8-SOIC package with a width of 0.154 inches (3.90mm). Maximum propagation delay is 50ns, with typical rise/fall times of 2.5ns. Pulse-width distortion is limited to 3ns maximum. Operating temperature ranges from -40°C to 125°C.

Feature Summary

• Implements magnetic coupling via iCoupler technology for high-speed signal transmission
• Provides bidirectional communication capabilities with 3V/5V level translation
• Offers precise timing characteristics including low pulse-width distortion
• Ensures high common-mode transient immunity for noise rejection

Applications

• Industrial automation systems requiring galvanic isolation
• Medical equipment needing certified safety isolation
• Automotive electronics interfaces
• General-purpose digital isolation in noisy environments

Procurement Notes

Verify the specific suffix WTRZ55 against official Analog Devices documentation to confirm packaging and tape-and-reel specifications. Confirm current manufacturing status as variants may be obsolete or superseded by newer revisions. Ensure compliance with RoHS directives and check for any recent Product Change Notices affecting this specific part number before procurement.

Selection Notes

Select this component when dual-channel isolation with unidirectional data flow (2 inputs, 0 outputs on secondary side) is required. It is suitable for applications demanding high CMTI and low power consumption at varying data rates. Compare against ADUM1201 if bidirectional channels are needed instead of the fixed 2/0 configuration provided by the ADUM1200 series.

Part Context

The ADUM1200 series belongs to Analog Devices' iCoupler family, which integrates monolithic transformer technology onto CMOS chips. This approach replaces traditional optocouplers, offering superior performance in speed, power efficiency, and reliability. The WTRZ55 designation indicates a specific tape-and-reel packaging variant within the broader ADUM1200 product line.

Replacement Considerations

Public confirmed substitute part numbers include ADUM1200WURZ and ADUM1200WURZ-RL7. These alternatives offer parameter equivalence but may differ in packaging format or reel quantity. Verify pinout compatibility and electrical specifications against the original datasheet before substitution.
