ADUM1402CRW Digital Isolator from Analog Devices Inc.

The ADUM1402CRW is a high-performance, quad-channel digital isolator manufactured by Analog Devices Inc., designed to offer superior isolation in a wide range of applications. This robust component uses Analog Devices' iCoupler® technology to facilitate signal transfer across an isolation barrier, ensuring that sensitive digital circuits are protected from high voltages and noise that can be present in industrial, medical, and other harsh environments.

With its four independent isolation channels, the ADUM1402CRW provides a flexible solution for systems that require multiple isolated signals. Each channel is capable of transferring data at speeds up to 10 Mbps, making it suitable for high-speed digital interfacing. The device supports both 3.3V and 5V supply voltages, which allows for easy integration into various system designs without the need for additional level shifting.

The ADUM1402CRW comes in a compact 16-lead SOIC wide-body package, which ensures a minimum of 8mm creepage and clearance distances for reliable operation even under high-voltage conditions. This makes it an excellent choice for applications that must adhere to stringent safety standards, such as industrial control systems, isolated SPI interfaces, and medical equipment where patient safety is of paramount importance.

Key features of the ADUM1402CRW include:

• Quad-channel bidirectional isolator
• Data rates up to 10 Mbps
• High-temperature operation: -40°C to +125°C
• High-voltage isolation: 2500 Vrms for 1 minute
• Low power consumption
• Robust EMC performance
• 16-lead SOIC wide-body package

Designed with safety in mind, the ADUM1402CRW has approvals from regulatory agencies, including UL, CSA, VDE, and CQC, which certify its reliability and suitability for use in safety-critical systems. The combination of high-speed performance, low power consumption, and robust isolation capabilities make the ADUM1402CRW an ideal choice for engineers looking to enhance the safety and integrity of their digital systems.
