ADuM3220是采用ADI公司iCoupler技术的4 A隔离式双通道栅极驱动器。该隔离器件将高速CMOS与单芯片变压器技术融为一体，具有优于脉冲变压器和栅极驱动器组合等替代器件的出色性能特征。
ADuM3220提供两个独立的隔离通道。它具有60 ns的最大传播延迟和5 ns的通道间匹配。与采用高压电平转换方法的栅极驱动器相比，ADuM3220的输入与各输出之间具有真电流隔离优势，能够跨越隔离栅实现电压转换。ADuM3220具有直通保护逻辑和栅极驱动应用所要求的默认低电平输出特性。该器件采用3.0 V至5.5 V电源电压工作，可与低压系统兼容。输出可采用5 V至18 V的电源，支持同步DC/DC转换器的典型栅极驱动电压。
AduM3220隔离器包含各种电路和布局改进，系统级IEC 61000-4-x测试（ESD、突发和浪涌）显示其性能大大增强。这些测试的精度主要取决于用户电路板或模块的设计与布局。欲了解更多信息，请参考应用笔记AN-793：“iCoupler隔离产品的ESD/闩锁考虑因素”。ADuM3220规定结温范围为?40°C至125°C。
