A1204LUA-T传感器变送器的磁性传感器-开关（固态）规格书PDF中文资料

A1204LUA-T属于传感器变送器的磁性传感器-开关（固态）。由Allegro MicroSystems制造生产的A1204LUA-T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。

Description

The Allegro® A1201, A1202, A1203, and A1204 Hall-effect bipolar switches are next-generation replacements and extension of the popular Allegro A3134, A3133, and A3132 bipolar switch product line. Overall, the A120x family, produced with BiCMOS technology, consists of continuous-time devices that feature fast power-on time and low-noise operation. Device programming is performed after packaging, to ensure increased switchpoint accuracy by eliminating offsets that can be induced by package stress. Unique Hall element geometries and low offset amplifiers help to minimize noise and to reduce the residual offset voltage normally caused by device overmolding, temperature excursions, and thermal stress.
