ADuM1440/ADuM1441/ADuM1442/ADuM1445/ADuM1446/ADuM1447 是采用ADI公司
iCoupler®技术的微功耗、
4-channel digital isolator。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。 EN
X信号可用于禁用内部刷新,从而将总静态电流降低至不足1 µA。
The ADuM1440/ADuM1441/ADuM1442/ADuM1445/ADuM1446/ADuM1447 family of quad-channel 2.5 kV digital isolation devices are available in small 16-pin QSOP and 20-pin SSOP packages. While most quad isolators are available in a 16-pin SOIC wide-body package, the ADuM1440/ADuM1441/ADuM1442/ADuM1445/ADuM1446/ADuM1447 saves nearly 70% of board space while still withstanding high isolation voltages and complying with regulatory requirements such as UL and CSA standards (pending). In addition to saving space, the ADuM1440/ADuM1441/ADuM1442/ADuM1445/ADuM1446/ADuM1447 can be powered from a supply as low as 2.25 V.
In addition to low power consumption, all models of the ADuM1440/ADuM1441/ADuM1442/ADuM1445/ADuM1446/ADuM1447 have very low pulse width distortion (less than 8 ns). In addition, each model offers an input glitch filter to prevent extraneous noise interference.
