ADUM5403WCRWZ-RL | Quad Channel Digital Isolator with Integrated DC/DC | isoPower® Interface IC

Product Overview

     The ADUM5403WCRWZ-RL is a quad-channel digital isolator from Analog Devices featuring isoPower® technology — an integrated isolated DC-to-DC converter that eliminates the need for a separate isolated power supply in many system designs. Using high-speed magnetic coupling and iCoupler® technology, the device provides robust digital signal isolation and up to 500 mW of regulated isolated power from a single input supply. It supports data rates up to 25 Mbps and voltage isolation of 2500 Vrms, making it ideal for industrial, automotive, and mixed-signal systems requiring reinforced isolation.

Key Features

• 4 independent digital isolation channels for logic signal separation
• isoPower® integrated isolated DC/DC converter up to ~500 mW
• Supports up to 25 Mbps non-return-to-zero (NRZ) data rate
• Reinforced isolation 2500 Vrms per UL 1577 standard
• High common-mode transient immunity (> 25 kV/µs)
• Regulated 5 V or 3.3 V isolated output from a 5 V input
• Low propagation delay (~60 ns typical)
• Wide supply range: 3.5 V to 5.5 V
• Industrial/automotive temperature range (–40 °C to +105 °C)
• Compact 16-pin SOIC package, compatible with board-level isolation creepage requirements

Applications

• Isolated digital interfaces (SPI, I²C with proper translators)
• Motor drives and gate driver isolation
• Battery management systems (BMS)
• Industrial fieldbus and PLC system isolation
• RS-232/RS-422/RS-485 transceivers
• Sensor and data acquisition isolation
• Power supply bias and startup circuits requiring isolation
