ADUM1286BRZ-RL7 Digital Isolator by Analog Devices Inc.

The ADUM1286BRZ-RL7 is a high-performance, dual-channel digital isolator designed and manufactured by Analog Devices Inc., a leader in high-performance semiconductors for signal processing applications. This product is part of their iCoupler® family and provides robust isolation for digital signals, ensuring system safety and signal integrity in a variety of demanding applications.

The ADUM1286BRZ-RL7 utilizes Analog Devices' patented iCoupler technology to achieve isolation by employing magnetic coupling through a chip-scale transformer, rather than relying on optoelectronic technology. This innovative approach allows for lower power consumption, improved data rates, and enhanced reliability over a wide temperature range.

This digital isolator offers two independent isolation channels in a bidirectional configuration, which makes it an excellent choice for isolating I2C or SPI interfaces, as well as other serial communication protocols that require a bidirectional data flow. The device supports a wide supply voltage range from 3.0V to 5.5V, enabling compatibility with various logic levels and providing design flexibility.

Key features of the ADUM1286BRZ-RL7 include:

• High-speed operation with data rates up to 25 Mbps
• Robust isolation with a withstand voltage rating of 2500 Vrms for 1 minute
• Low power operation and 5 ns maximum pulse width distortion
• High common-mode transient immunity >25 kV/μs
• Compact 8-lead SOIC package with a small footprint for space-constrained applications
• UL, CSA, VDE, and CQC certified for safety

Designed for ease of implementation, the ADUM1286BRZ-RL7 comes in a RoHS-compliant, surface-mount package that is suitable for automated assembly processes. The device is provided in reel packaging (RL7), facilitating efficient handling and manufacturing for high-volume production.

Applications that can benefit from the ADUM1286BRZ-RL7 include industrial automation, medical equipment, power supply control, and any other system that requires reliable signal isolation to protect sensitive electronics from high voltages and noise. By choosing the ADUM1286BRZ-RL7, designers can ensure robust performance and safety in their digital communication interfaces.
