ADUM1200WTRZ33

Overview

The ADUM1200WTRZ33 is a dual-channel digital isolator utilizing iCoupler magnetic coupling technology. It provides 2500Vrms isolation with a data rate of 10Mbps and a common-mode transient immunity of 25kV/µs. The device operates on a supply voltage range of 3V to 5.5V, featuring unidirectional channel directionality (2/0). Key timing parameters include a maximum propagation delay of 50ns and typical rise/fall times of 2.5ns. It is housed in an 8-SOIC package and supports an operating temperature range from -40°C to +125°C.

Feature Summary

• Integrates dual-channel isolation using proprietary iCoupler magnetic coupling technology for high-speed signal transmission.
• Delivers robust noise immunity with a minimum common-mode transient immunity rating of 25kV/µs.
• Supports wide operating voltage ranges and extended industrial temperature environments within a compact surface-mount package.

Applications

• Industrial automation control systems requiring galvanic isolation
• Medical equipment signal interface circuits
• Power supply feedback loop isolation

Procurement Notes

Verify the specific suffix '33' against official Analog Devices documentation to confirm pinout and electrical characteristics match design requirements. Confirm current availability status as distribution channels may list obsolete or alternative variants. Ensure compliance with RoHS directives and moisture sensitivity levels specified in the manufacturer's datasheet before procurement.

Selection Notes

Select this component when bidirectional isolation is not required, as it features fixed unidirectional channels. Compare performance metrics such as propagation delay and power consumption against other iCoupler series members like the ADUM1200WSRZ if higher data rates are needed. Validate that the 8-SOIC footprint aligns with existing PCB layout constraints and thermal management strategies.

Part Context

This part belongs to the ADUM1200 family of general-purpose digital isolators. It shares architectural similarities with variants like the ADUM1200WURZ but differs in specific packaging or tape-and-reel configurations. The product line emphasizes low power consumption and high reliability for isolated communication interfaces in noisy environments.

Replacement Considerations

Public confirmed substitute part numbers include ADUM1200WURZ and ADUM1200WTRZ. Verify parameter equivalence regarding data rate and isolation voltage before substitution.
