ADUM1402CRWZ Digital Isolator by Analog Devices Inc.

The ADUM1402CRWZ is a robust, high-performance digital isolator designed by Analog Devices Inc., a leader in high-performance semiconductors for signal processing applications. This product is part of the ADuM140x series, which are quad-channel digital isolators with integrated, isolated power. The ADUM1402CRWZ model specifically offers four independent isolation channels in a wide-body 16-lead SOIC package, ensuring reliable signal isolation in a compact form factor.

Constructed with Analog Devices Inc.'s proprietary iCoupler® technology, the ADUM1402CRWZ provides superior isolation capabilities. This technology utilizes magnetic coupling through a chip-scale transformer, unlike optocouplers that rely on light as a means of transferring signals across an isolation barrier. The result is a digital isolator that can operate at higher data rates, with lower power consumption, and enhanced robustness against environmental factors.

Key features of the ADUM1402CRWZ include:

• High data rate: up to 10 Mbps
• Wide supply voltage range: 2.7 V to 5.5 V
• Low power operation: 1.3 mA per channel at 1 Mbps
• High-temperature operation: rated for -40°C to +125°C
• High common-mode transient immunity: >25 kV/μs
• Robust EMC performance: complies with IEC 61000-4-x standards
• Quad-channel configuration: 4 forward-direction channels

The isolator's channels are capable of transmitting data in one direction, from "side A" to "side B," which is ideal for digital isolation in applications such as SPI communication, sensor interfaces, and industrial automation systems where unidirectional data flow is required. Additionally, the ADUM1402CRWZ is certified with reinforced insulation per VDE V 0884-10 and UL1577, ensuring that it meets stringent safety requirements for electrical isolation.

With its high integration, the ADUM1402CRWZ reduces board space and system design complexity, making it a preferred choice for engineers looking to implement isolation in their digital communication systems without compromising performance or reliability. Whether it's used in industrial, medical, or automotive applications, the ADUM1402CRWZ stands out as a durable and efficient solution for electrical signal isolation.
