AS5130: 8-bit Rotary Position Sensor With Digital Interface and PWM Output

The AS5130 is a contactless magnetic rotary position sensor (previously known as encoder) for accurate angular measurement over a full turn of 360° and over an extended ambient temperature of -40°C to +150°C. The absolute angle measurement provides instant indication of the magnet’s angular position with a resolution of 8 bit = 256 positions per revolution via a serial bit stream and as a PWM signal. The AS5130 can be operated in pulsed mode (Vsupply=off) allowing very low power consumption during polling of the rotary position of the magnet.
