ADuM3220/ADuM3221 是基于ADI公司 iCoupler®技术的4 A隔离式双通道门极驱动器。这些隔离器件结合了高速CMOS工艺和单片变压器技术，能够提供比脉冲变压器和门极驱动器组合等其它解决方案更优异的性能特性。
ADuM3220/ADuM3221隔离器提供两个独立的隔离通道。最大传播延迟为60 ns，通道间匹配为5 ns。与采用高压电平转换方法的门极驱动器相比，ADuM3220/ADuM3221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功能。ADuM3220具有直通保护逻辑，ADuM3221则没有。两款器件均提供门极驱动应用所需的默认低电平输出特性。ADuM3220/ADuM3221的输入电源电压范围为3.0 V至5.5 V，与低压系统兼容。ADuM3220A/ADuM3221A的输出电源电压范围为5 V至18 V。DuM3220B/ADuM3221B的输出电源电压范围为8 V至18 V。
ADuM3220/ADuM3221的额定结温范围为−40°C至+125°C。
