Overview
The ADUM5401WCRWZ-1RL is a quad-channel digital isolator produced by Analog Devices Inc., featuring integrated isoPower technology. This device combines high-speed digital isolation with an isolated DC-to-DC converter, eliminating the need for a separate isolated power supply in low-power designs. It is based on Analog Devices' iCoupler chip scale transformer technology, which ensures reliable isolation of logic signals and power supply.
