ADUM1201BR-RL7

Overview

The ADUM1201BR-RL7 is a dual-channel digital isolator utilizing iCoupler magnetic coupling technology. It features unidirectional data transmission with a data rate of 25 Mb/s and an insulation voltage of 2500 Vrms. The device operates within a supply voltage range of 2.7 V to 5.5 V, drawing a typical operating current of 6.3 mA. Key electrical specifications include a propagation delay of 50 ns, rise/fall times of 3 ns, and a pulse width of 100 ns. It is housed in an SOIC-8 package and supports an operating temperature range from -40°C to +105°C.

Feature Summary

• Dual-channel digital isolation with 1/1 channel directionality
• High-speed data transmission capability up to 25 Mb/s
• Robust galvanic isolation barrier based on iCoupler technology

Applications

• Industrial process control systems requiring signal isolation
• Medical equipment needing high-voltage isolation barriers
• Power metering applications for accurate signal transfer

Procurement Notes

Verify the specific suffix 'RL7' indicates reel packaging when sourcing. Confirm that this part number is obsolete and check for direct substitutes like ADUM1201BRZ-RL7. Ensure compatibility with existing PCB footprints and design-in requirements before procurement.

Selection Notes

Select this component for applications requiring bidirectional logic isolation where unidirectional channels suffice. Compare propagation delay and power consumption against other iCoupler variants. Verify that the SOIC-8 package fits the mechanical constraints and thermal management needs of the target design.

Part Context

This device belongs to the ADuM1201 series of dual-channel digital isolators. It leverages Analog Devices' proprietary iCoupler technology to provide isolation without external transformers or optocouplers. The series is designed for general-purpose isolation in noisy environments.

Replacement Considerations

The ADUM1201BR-RL7 is listed as obsolete. Direct substitute part numbers include ADUM1201BRZ-RL7. Verify pinout and electrical specifications match before substitution.
