Overview
The ADUM2402CRIZ is a quad-channel digital isolator produced by Analog Devices Inc. It is based on Analog Devices' iCoupler® technology, which provides high-speed digital isolation with low pulse width distortion and tight channel-to-channel matching. This component is designed to operate in a wide range of supply voltages from 2.7 V to 5.5 V, making it compatible with various system voltages and enabling voltage translation across the isolation barrier. The ADUM2402CRIZ is packaged in a 16-pin SOIC (Small Outline Integrated Circuit) package with increased creepage distance, ensuring robust isolation and reliability.
