ADUM1300WSRWZ35

Overview

The ADUM1300WSRWZ35 is a digital isolator from Analog Devices, utilizing magnetic coupling technology to provide electrical isolation between circuits. It features three independent channels configured for unidirectional signal transmission (3 transmitters, 0 receivers). The device operates within a supply voltage range of 2.7 V to 5.5 V and supports data rates up to 90 Mb/s. Key electrical specifications include an insulation voltage of 2500 Vrms, a propagation delay of 100 ns, and a common-mode transient immunity of 25 kV/µs. It is qualified under AEC-Q100 standards for automotive applications and functions reliably across an extended temperature range from -40°C to +125°C.
