AEAT-8800-Q24

AEAT-8800-Q24 is a 10- to 16bit programmable angular magnetic encoder IC. It provides accurate angular measurement over a full 360 degrees of rotation. It is a sophisticated system that 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, placed in alignment to the center of the device. It is a versatile solution capable of supporting a broad range of applications with its robust architecture to measure and deliver both absolute and incremental signals. The absolute angle measurement provides an instant indication of the magnet's angular position with a selectable and one-time programmable resolution of 10, 12, 14, or 16 bits. Application includes brushless DC motor and stepper motor, resolver and potentiometer replacement, industrial automation and robotics, industrial sewing machine and textiles equipment.
