ADUM1400WSRWZ35

Overview

The ADUM1400WSRWZ35 is a quad-channel digital isolator utilizing iCoupler magnetic coupling technology. It provides four unidirectional signal channels with a data rate of 1 Mbps and a propagation delay of 100 ns. The device operates on a supply voltage range of 2.7 V to 5.5 V, drawing typical currents of 18 mA and 70 mA for the respective sides. It features an isolation voltage of 2500 Vrms and a common-mode transient immunity (CMTI) exceeding 25 kV/µs. Packaged in a 16-SOIC surface-mount format, it supports an operating temperature range from -40°C to +125°C.
