ADUM1201WTRZ35-RL7

Overview

The ADUM1201WTRZ35-RL7 is a dual-channel digital isolator from Analog Devices, utilizing iCoupler magnetic coupling technology. It operates within a supply voltage range of 2.7 V to 5.5 V and provides bidirectional data transmission with a maximum data rate of 1 Mbps. The device features a common-mode transient immunity (CMTI) of 25 kV/µs and an isolation voltage rating of 2500 Vrms. Packaged in an 8-SOIC surface-mount footprint, it supports unidirectional channel configurations and functions across an extended industrial temperature range from -40°C to +125°C.

Feature Summary

• Integrates two independent digital isolation channels using proprietary iCoupler magnetic coupling technology for signal transmission.
• Provides high reliability with a 2500 Vrms isolation voltage rating and robust 25 kV/µs common-mode transient immunity.
• Supports low-power operation with a wide supply voltage range of 2.7 V to 5.5 V and minimal quiescent current consumption.
• Delivers consistent signal integrity with symmetrical propagation delays and low pulse width distortion characteristics.

Applications

• Industrial automation systems requiring galvanic isolation between microcontrollers and peripheral sensors
• Medical equipment interfaces needing certified isolation barriers for patient safety compliance
• Automotive electronics applications demanding high noise immunity and wide operating temperature ranges

Procurement Notes

Verify the specific suffix '35' against the manufacturer's latest documentation to confirm pinout and electrical specifications, as variations exist within the ADUM1201 family. Confirm availability status directly with authorized distributors, as this component may be subject to limited supply or discontinuation notices. Ensure the reel packaging format matches your automated assembly requirements before finalizing orders.

Selection Notes

Select this component when a dual-channel solution with 1 Mbps data rate and 2500 Vrms isolation is required. Compare against the standard ADUM1201WTRZ if higher speed performance up to 10 Mbps is needed instead. Consider the AEC-Q100 qualification status for automotive deployment scenarios. Evaluate the 8-SOIC package dimensions against PCB layout constraints to ensure adequate creepage and clearance distances are maintained.

Part Context

This part belongs to the ADUM1201 series of dual-channel digital isolators manufactured by Analog Devices. The series utilizes silicon-based magnetic coupling technology to replace traditional optocouplers, offering superior performance in terms of speed, power consumption, and size. The product line includes various packaging options and speed grades to suit different interface requirements.

Replacement Considerations

The ADUM121N1WBRZ is listed as a similar replacement option for discontinued variants within this family. Verify functional compatibility and pin alignment before substitution. Other members of the ADUM1200/1201 series may serve as alternatives depending on specific speed and isolation voltage requirements.
