A1262: 2D, Dual-Channel, Ultrasensitive Hall-Effect Latch

A1262是一个两个通道，锁定霍尔效应传感器IC，其具有垂直和平面霍尔元素。垂直和平面霍尔元件具有彼此正交的传感轴，并为环形磁铁提供90°的相分离，其固有地独立于磁极间隔和气隙。

The 2D architecture of the A1262 simplifies the design of motors and magnetic encoders by providing quadrature output signals in a very small footprint. The A1262 outputs allow the speed and direction of a rotating ring magnet to be determined.

The A1262 is available in two sensing options that allow flexibility in end-system magnetic design. Both options feature a planar Hall plate that is sensitive to magnetic fields perpendicular to the face of the package (Z). Two options of vertical Hall plate orientation (X or Y) in both packages offer flexibility in system design and magnet to sensor placement.

On a single silicon chip, the A1262 includes: voltage regulator, reverse battery protection, two Hall plates (one planar and one vertical), a multiplexer, a small-signal amplifier, chopper stabilization, a Schmitt trigger, and two short-circuit protected open-drain outputs that can sink up to 20 mA continuously.

A1262的两个温度范围：-40°C至85°C（E温度范围选项）或-40°C至150°C（L温度范围选项）。

A1262配有5引脚SOT23W表面安装封装（LH）和4针SIP封装（K）。每个都以各种磁铁提供两种选择，以传感器方向。封装是符合RoHS的RoHS和引线（PB），100％哑光锡引线框架。
