微功耗四通道数字隔离器，默认高电平（3/1通道方向性）

ADuM1440/ADuM1441/ADuM1442/ADuM1445/ADuM1446/ADuM1447是采用ADI公司iCoupler®技术的微功耗、4通道数字隔离器。这些隔离器件将高速互补金属氧化物半导体(CMOS)与单芯片空芯变压器技术融为一体，具有优于光耦合器等替代器件的出色性能特征。如数据手册中的图3所示，在标准工作模式下，当ENx = 0（内部刷新使能）时，每通道电流低于10 µA。当ENx = 1（内部刷新禁用）时，每通道电流降至1 µA以下。\n\n ADuM1440/ADuM1441/ADuM1442/ADuM1445/ADuM1446/ADuM1447系列四通道 • 超低功耗：\n• 3.3 V（典型值）：\n• 5.6 μA（每通道静态电流，使能刷新）\n\n• 0.3 μA（每通道静态电流，禁用刷新）\n\n• 148 μA/Mbps（每通道典型动态电流）\n\n\n\n\n• 2.5 V（典型值）：\n• 3.1 μA（每通道静态电流，使能刷新）\n\n• 0.1 μA（每通道静态电流，禁用刷新）\n\n• 117 μA/Mbps（每通道典型动态电流）\n\n\n\n\n\n\n\n• 小型16引脚QSOP和20引脚SSOP封装\n\n• 双向通信\n\n• 数据速率最高可达2 Mbps (NRZ);
