AH180-W传感器变送器的磁性传感器-开关（固态）规格书PDF中文资料

AH180-W属于传感器变送器的磁性传感器-开关（固态）。由美台半导体制造生产的AH180-W磁性传感器 - 开关（固态）该系列产品使用固态技术来检测是否存在超过某个特定幅度和/或标示的磁场，并提供指示是否存在此类磁场的双态输出。它们与磁簧开关以及线性或罗盘型固态器件不同，前者通过使用移动机械部件来提供类似的功能，后者提供指示所施加磁场的强度和/或方向的可变输出。

描述 Description

AH180 is a micro-power Omnipolar Hall-Effect switch designed for portable and battery powered equipment such cellular phones, PDAs and portable PCs. Based on two Hall-Effect plates and a chopper stabilized architecture the AH180 provides a reliable solution over the whole operating ange. To support portable and battery powered equipment the design has been optimized to operate over the supply range of 2.5V to 5.5V and consumes only 24uW with a supply of 3V.
