ADUM1250SRZ

The Analog Devices ADUM1250SRZ is a digital isolator designed for I2C interfaces, offering robust isolation and bidirectional communication. This device provides 2500Vrms of isolation, ensuring signal integrity and protection in noisy environments.

Key electrical specifications include a data rate of up to 1Mbps and a high common-mode transient immunity of 25kV/µs. It supports bidirectional I2C communication across two channels, simplifying designs that require isolated I2C, SMBus, or PMBus interfaces. The isolator operates with supply/logic levels ranging from 3.0V to 5.5V and features a current sink capability of 30mA.

Designed for reliability, the ADUM1250SRZ operates across a wide temperature range of -40°C to 125°C. It is housed in a compact 8-SOIC surface-mount package, measuring 0.154 inches (3.90mm) in width, making it suitable for space-constrained applications. The device is qualified for automotive applications and meets stringent safety and regulatory standards.

This isolator is ideal for applications such as isolated I2C interfaces, multilevel I2C systems, power supplies, networking equipment, Power over Ethernet, and hybrid electric vehicle battery management systems. Its magnetic coupling technology offers advantages in performance and size compared to traditional optocouplers.
