Digital Isolators

ADUM221N1BRWZ Description

The ADUM221N1BRWZ from Analog Devices Inc. is a high-performance, dual-channel digital isolator from the iCoupler® series, leveraging magnetic coupling technology to deliver robust isolation up to 5000Vrms. Designed for general-purpose applications, it supports a wide supply voltage range of 1.7V to 5.5V, making it versatile for mixed-voltage systems. With a data rate of 150Mbps and ultra-low propagation delay (13ns max), it ensures high-speed signal integrity while maintaining excellent common-mode transient immunity (75kV/µs). The device is ROHS3 compliant and housed in a 16-SOIC package, suitable for surface-mount assembly.

ADUM221N1BRWZ Features

• High-Speed Performance: Achieves 150Mbps data throughput with minimal pulse width distortion (<3ns) and symmetrical rise/fall times (2.5ns).
• Robust Isolation: 5000Vrms isolation rating and 75kV/µs CMTI ensure reliability in noisy environments.
• Wide Voltage Compatibility: Operates from 1.7V to 5.5V, ideal for interfacing between low-voltage MCUs and higher-voltage peripherals.
• Unidirectional Channels: Two independent unidirectional channels simplify design for signal transmission.
• Compact & Reliable: 16-SOIC package with MSL 3 rating, suitable for industrial and automotive applications.
