ADUM1200WSRZ33-RL7

Overview

The ADUM1200WSRZ33-RL7 is a dual-channel digital isolator utilizing iCoupler magnetic coupling technology. It features 2/0 channel directionality and supports data rates up to 1 Mbps. The device operates on a supply voltage range of 3V to 5.5V with a typical quiescent current of 4.3 mA per channel. It provides an isolation voltage of 2500 Vrms and a common-mode transient immunity (CMTI) of 25 kV/µs. Maximum propagation delay is 150 ns, with rise/fall times of 10 ns. It is housed in an 8-SOIC package and qualified for automotive applications under AEC-Q100 standards.

Feature Summary

• Implements iCoupler magnetic coupling technology for high-speed signal transmission without external magnetics
• Provides robust galvanic isolation with 2500 Vrms insulation voltage rating
• Features unidirectional 2/0 channel configuration for specific directional data flow requirements
• Delivers high common-mode transient immunity of 25 kV/µs to maintain signal integrity in noisy environments

Applications

• Automotive electronic control units requiring isolated communication interfaces
• Industrial systems needing reliable data isolation between microcontrollers and peripherals
• Medical equipment designs requiring certified galvanic isolation for safety compliance

Procurement Notes

Verify the complete part number includes the '33' suffix, which denotes a specific internal configuration or variant within the ADUM1200 family. Confirm that the WSRZ designation matches the required SOIC-8 wide-body package and reel packaging format. Ensure the component meets AEC-Q100 automotive qualification standards if deployed in vehicle electronics. Cross-reference the manufacturer's latest datasheet to confirm pinout compatibility and electrical specifications before integration into final designs.

Selection Notes

Select this component when a dual-channel unidirectional isolator with 1 Mbps speed is required. It is suitable for applications demanding 2500 Vrms isolation and automotive reliability. Consider the 8-SOIC package constraints and 4.3 mA power consumption per channel. Compare against standard ADUM1200 variants if the '33' suffix indicates a non-standard configuration. Evaluate CMTI requirements against the 25 kV/µs specification for noise immunity needs.

Part Context

This part belongs to the Analog Devices ADuM1200 series of iCoupler digital isolators. The series combines CMOS sensor technology with monolithic air-core transformer capabilities. The ADUM1200 specifically offers two independent channels with unidirectional data flow. It serves as a cost-effective alternative to optical isolators in space-constrained designs.
