  • ADUM3211- 双通道数字隔离器，具有增强的系统级ESD可靠性
    ADUM3211: 双通道数字隔离器，具有增强的系统级ESD可靠性

    ADuM321x1是一款双通道数字隔离器，基于ADI公司的iCoupler® 技术。这款器件结合了高速CMOS工艺和单片式变压器技术，具有优于光耦合器等替代器件的卓越性能特性。

    由于避免了使用光耦合器和LED，iCoupler器件消除了通常与光耦合器相关的设计难题，如电流转移率的不确定性、非线性传递函数以及温度和使用寿命对性能的影响等问题，利用简单的iCoupler数字接口和稳定的性能特性，这些问题都迎刃而解。采用iCoupler产品不再需要外部驱动器和其它分立器件。而且，在相当的信号数据速率下，iCoupler器件的功耗仅为光耦合器的1/10到1/6。

    ADuM321x提供两个独立的隔离通道。两端的电源电压范围均为2.7V到5.5V，可与低电压系统兼容，并可实现通过隔离的电压转换功能。与ADuM3200/ ADuM320 MoreRead more
