ams AS5045B
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, combining integrated Hall elements, analog front end and digital signal processing in a single device. The magnet can be placed above or below the IC.| Part No. | AS5045B |

GENERAL DESCRIPTION
To measure the angle, only a simple two-pole magnet, rotating over the center of the chip, is required. The magnet can be placed above or below the IC. The absolute angle measurement provides instant indication of the magnet’s angular position with a resolution of 0.0879º = 4096 positions per revolution. This digital data is available as a serial bit stream and as a PWM signal. An internal voltage regulator allows the AS5045B to operate at either 3.3V or 5V supplies. 2 KeyFEATURES
