Overview
The ADuM3220BRZ-RL7, produced by Analog Devices Inc., is an isolated, 4 A dual-channel gate driver. This component utilizes Analog Devices' iCoupler technology, which combines high-speed CMOS and monolithic transformer technology to provide superior performance characteristics. The ADuM3220 offers true galvanic isolation between the input and each output, enabling voltage translation across the isolation barrier. This makes it particularly suitable for applications requiring high-speed and reliable isolation.
