Product details

ADuM1445是具有默认低电平和4/1通道方向性的微功耗、Quad digital isolator，其基于ADI公司iCoupler®技术（提供双通道产品）。这些隔离器件结合了高速互补金属氧化物半导体(CMOS)与单片空芯变压器技术，可提供出色的性能特性，优于光耦器件和其它集成式耦合器，同时在现有的所有隔离产品中功耗最低。 ENXThe signal can be used to disable internal flush, reducing the total quiescent current to less than 1 μA.

ADuM1440/ADuM1441/ADuM1442/ADuM1445/ ADuM1446/ADuM1447系列四通道2.5 kV数字隔离器件采用小型16引脚QSOP和20引脚SSOP封装。大部分四通道隔离器采用16引脚SOIC宽体封装，而相比之下，ADuM1440/ ADuM1441/ADuM1442/ADuM1445/ADuM1446/ADuM1447可节省几乎70%的电路板空间，却仍能耐受高隔离电压，并且符合UL和CSA标准（正在申请中）等法规要求。除了节省空间外，ADuM1440/ADuM1441/ADuM1442/ADuM1445/ ADuM1446/ADuM1447还可采用低至2.25 V的电源供电。

In addition to low power, all ADuM1440/ADuM1441/ADuM1442/ADuM1445/ADuM1446/ADuM1447 models have very low pulse width distortion (less than 8 ns). In addition, each model provides an input glitch filter to protect against extraneous noise.
