Product details

ADuM1445 – это микроусилитель с низкой направленностью по умолчанию и направленностью 4/1 канала,Quad digital isolator, которая основана на технологии iCoupler® компании Analog Devices, которая предлагает двухканальные продукты. Эти изолирующие устройства сочетают в себе высокоскоростной комплементарный металл-оксидный полупроводник (КМОП) с монолитной технологией трансформатора с воздушным сердечником, чтобы обеспечить превосходные эксплуатационные характеристики, которые превосходят оптопары и другие интегрированные соединители, потребляя при этом самую низкую мощность среди всех существующих изоляционных продуктов. ЭНXThe signal can be used to disable internal flush, reducing the total quiescent current to less than 1 μA.

Семейство четырехъядерных цифровых изолированных устройств с напряжением 2.5 кВ ADuM1440/ADuM1441/ADuM1442/ADuM1442/ADuM1445/ ADuM1446/ADuM1447 выпускается в компактных 16-выводных корпусах QSOP и 20-выводных SSOP. По сравнению с ADuM1440/ADuM1441/ADuM1442/ADuM1445/ADuM1446/ADuM1447, которые экономят почти 70% места на плате в большинстве четырехвыводных широкофюзеляжных корпусов SOIC, ADuM1446/ADuM1447 по-прежнему выдерживают высокие напряжения изоляции и соответствуют нормативным требованиям, таким как стандарты UL и CSA (в стадии рассмотрения). ADuM1440/ADuM1441/ADuM1442/ADuM1445/ ADuM1446/ADuM1447 могут работать от напряжения питания до 2.25 В.

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.
