Broadcom AEAT-9955
10- to 18-Bit programmable angular magnetic encoder
The Broadcom AEAT-9955 is an angular magnetic rotary sensor that provides accurate angular measurement over a full 360 degrees of rotation. A sophisticated system uses integrated Hall sensor elements with complex analog and digital signal processing within a single device. A simple two-pole magnet generates the necessary magnetic field by rotating it in perpendicular. Wide magnetic field sensor configurations allow On Axis (end of shaft) or Off Axis (side of shaft, axial and radial) modes in applications.
