AS5045B Overview
The AS5045B is a contact less magnetic position sensor for accurate angular measurement over a full turn of 360 degrees. It is a system-on-chip, bining integrated Hall elements, analog front end and digital signal processing in a single device. To measure the angle, only a simple two-pole magnet, rotating over the center of the chip, is required.
