The AS5045B is a 12-bit programmable magnetic position sensor designed for accurate angular measurement over a full 360-degree turn. This system-on-chip integrates Hall elements, analog front end, and digital signal processing, requiring only a simple two-pole magnet for operation. It offers absolute angle measurement with a resolution of 0.0879 degrees (4096 positions per revolution) and provides digital data via a serial bit stream or a PWM signal. The device supports both 3.3V and 5V supply voltages.
