Overview
The ADUM7641ARQZ-RL7 is a 6-channel digital isolator manufactured by Analog Devices Inc. This device is based on Analog Devices' iCoupler® technology, which combines high-speed CMOS and monolithic air core transformer technology to provide reliable and efficient data isolation. The ADUM7641ARQZ-RL7 is packaged in a compact 20-lead QSOP, offering significant space savings and a lower cost compared to higher isolation voltage solutions when only functional isolation is required.
