The ADUM1251ARZ-RL7 is a hot-swappable digital isolator from Analog Devices, featuring two bidirectional I2C communication channels. This device is based on iCoupler® chip scale transformer technology, providing a robust and compact solution for isolated I2C, SMBus, or PMBus interfaces.
Key electrical specifications include a supply voltage range of 3.0V to 5.5V, a data rate of 1Mbps, and a high common mode transient immunity of 25kV/µs. The isolator provides 2500Vrms of isolation for 1 minute, suitable for applications requiring high voltage separation. It operates within a temperature range of -40°C to 105°C.
This digital isolator is available in an 8-lead SOIC package, measuring 0.154" (3.90mm) wide, and is suitable for surface mount applications. Its design incorporates hot-swap circuitry to prevent data glitches during insertion into active buses, making it ideal for power supplies, networking, and automotive applications like hybrid electric vehicle battery management.
