Overview
The ADUM5241ARZ from Analog Devices Inc. is a dual-channel digital isolator that integrates an isolated DC-to-DC converter using the company's iCoupler® technology. This component is designed to provide reliable and efficient signal isolation and power transfer in various applications. The ADUM5241ARZ features a chip-scale DC-to-DC converter that delivers up to 50 mW of regulated, isolated power at 5 V, eliminating the need for a separate isolated DC-to-DC converter in low-power isolated designs.
