ADUM4400ARWZ

ADUM4400ARWZ Description

The ADUM4400ARWZ from Analog Devices Inc. is a high-performance, quad-channel digital isolator utilizing magnetic coupling (iCoupler®) technology. Designed for general-purpose isolation, it delivers 5000Vrms of reinforced isolation, making it suitable for high-voltage environments. Operating from 3V to 5.5V, it supports 1Mbps data rates with low propagation delay (100ns max) and minimal pulse width distortion (40ns max). The device features unidirectional channels (4 inputs, 0 outputs) and offers exceptional common-mode transient immunity (25kV/µs), ensuring reliable signal integrity in noisy industrial settings. Packaged in a 16-SOIC tube, it is RoHS3 compliant and rated for MSL 1 (unlimited).
