描述

The A1266 integrated circuit is an ultrasensitive Hall-effect switch with 3D omnipolar magnetic actuation. The single silicon chip includes: three Hall plates, multiplexer, small-signal amplifier, chopper stabilization, Schmitt trigger, and NMOS output transistors. The device outputs turn on when a magnetic field of sufficient strength is applied to the sensor in any orientation. Removal of the magnetic field will turn the output off.

A1266的两个版本提供了一种输出格式的选择：单独的x，y和z输出，或组合x + y + z输出。低运行电源电压，2.5至5.5 V，独特的时钟算法有助于降低平均功耗，使其适用于电池操作（例如，使用3.3 V电源的功耗小于25μW）。

BICMOS工艺的小几何形状允许适用于甚至是空间受限应用的超超级封装。雷竞技最新网址在这种情况下，改进的SOT23-W表面安装封装可用3引脚（组合）或5引脚（单独的输出）配置，磁化以用于各种方向。封装是铅（Pb）的免费和符合RoHS兼容，100％哑光锡引线框架。
