i
Coupler®技术的双
通道数字隔离器。这些隔离器件将高速CMOS与单芯片变
压器技术融为一½,具有优于光耦合器等替代器件的出色
性½特征。
i
Coupler器件不用LED和光电二极管,因而不存在一般与
光耦合器相关的设计困难。简单的
i
Coupler数字接口和稳
定的性½特征,可消除光耦合器通常具有的电流传输比不
确定、非线性传递½数以及温度和½用寿½½响等问题。
这些
i
Coupler产品不需要外部驱动器和其它分立器件。此
外,在信号数据速率相½的情况下,
i
Coupler器件的功耗
只有光耦合器的1/10至1/6。
ADuM3200/ADuM3201隔离器提供两个独立的隔离通道,
支持多种通道配½和数据速率(请参考“订购指南”)。它们
的任一侧均可采用3.3
V至5 V电源电压工½,与½压系统兼

和ADuM3201W为½½应用级产品,工½温度可达125°C。
与ADuM120x隔离器相比,ADuM3200/ADuM3201隔离器
包含多项电路和布局改进,系统级IEC
