ADUM6404ARWZ by Analog Devices Inc.

The ADUM6404ARWZ is an innovative component from the esteemed Analog Devices Inc., a company known for its high-performance semiconductor products and solutions. This particular model is part of the ADuM640x series, which are quad-channel digital isolators with isoPower®, an integrated, isolated dc-to-dc converter. The ADUM6404ARWZ is designed to provide both high data rate digital isolation and isolated power in a single package, making it an ideal solution for a variety of applications that require robust isolation between the input and output sides.

Featuring Analog Devices Inc.'s proprietary iCoupler® technology, the ADUM6404ARWZ ensures reliable data transfer with high noise immunity. The device operates with an input supply voltage ranging from 3.0V to 5.5V, delivering a regulated output voltage of 5.0V through the integrated dc-to-dc converter, which can supply up to 500 mW of output power. This makes it suitable for powering multiple isolated channels in a system without the need for multiple isolated power supplies.

The isolator's channels are capable of transmitting data at rates up to 90 Mbps with low propagation delay, making it suitable for high-speed digital interfaces. Additionally, its default high output and three-state outputs provide a fail-safe feature in the event of input power loss, ensuring the system remains in a known state during fault conditions.

In terms of safety, the ADUM6404ARWZ offers reinforced insulation rated up to 5 kV RMS, which is essential for meeting stringent industrial safety requirements. The package is a 16-lead, wide-body SOIC package that guarantees a minimum of 8.3 mm of creepage and clearance, adhering to the requirements for system-level regulatory approvals.

Common applications for the ADUM6404ARWZ include industrial field buses, motor controls, power converters, and other situations where data integrity and isolation are critical. With its combination of power isolation, signal isolation, and a compact footprint, the ADUM6404ARWZ is a versatile and efficient solution for designers looking to enhance system performance while maintaining safety and reliability.
