ADUM4402CRIZ

ADUM4402CRIZ Description

The ADUM4402CRIZ from Analog Devices Inc. is a high-performance, quad-channel digital isolator utilizing magnetic coupling (iCoupler®) technology. Designed for general-purpose isolation, it supports 90Mbps data rates with robust 5kVrms isolation (UL-recognized) between channels. Operating from 3V to 5.5V, it ensures reliable signal transmission in noisy environments, featuring 25kV/µs common-mode transient immunity (CMTI) to reject interference. The device is ROHS3 compliant and housed in a 16-pin SOIC package, suitable for surface-mount applications.

ADUM4402CRIZ Features

• Quad-channel unidirectional isolation (2 inputs/2 outputs per side) for bidirectional system integration.
• Ultra-low propagation delay (max 32ns) and tight pulse width distortion (<2ns), critical for timing-sensitive designs.
• High-speed performance: 90Mbps data rate with 2.5ns rise/fall times, ideal for fast digital interfaces.
• No isolated power required, simplifying design vs. optocouplers.
• Wide supply range (3V–5.5V) and 5000Vrms isolation for industrial/compliance-heavy applications.
• 3 (168 Hours) MSL rating ensures reliability in humid environments.

ADUM4402CRIZ Applications

• Industrial automation: Isolate PLCs, motor drives, and sensors in high-noise environments.
• Medical equipment: Ensure patient safety in diagnostic devices with reinforced isolation.
• Power supplies: Isolate feedback loops in SMPS or inverters.
• Communication interfaces: Protect SPI, I²C, or UART lines in RS-485/CAN systems.
• Renewable energy: Isolate gate drivers in solar/wind power converters.

Conclusion of ADUM4402CRIZ

The ADUM4402CRIZ combines high-speed, robust isolation, and ease of integration, making it superior to optocouplers and lower-speed isolators. Its magnetic coupling technology eliminates LED degradation issues, while 5kVrms isolation meets stringent safety standards. Ideal for industrial, medical, and energy systems requiring reliable noise immunity and signal integrity.
