AS5245 Rotary Position Sensor

Redundant 12-Bit Rotary Position Sensor With Digital Angle (Interface) and ABI Output

The AS5245 is a redundant, contactless magnetic rotary position sensor for accurate angular measurement over a full turn of 360° and over an extended ambient temperature range of -40°C to 150°C. The absolute angle measurement provides instant indication of the magnet's angular position with a resolution of 0.0879° = 4096 positions per revolution via a serial bit stream and as a PWM signal.
