AS5030 Rotary Position Sensor

8-bit Rotary Position Sensor with Digital Angle (Interface) and PWM Output

The AS5030 is an 8-bit rotary position sensor (previously known as encoder) for absolute angular measurement over a full turn of 360° based on contactless magnetic sensor technology. This device fits perfectly for on-axis applications where a simple 2-pole magnet rotates above or below the sensor IC and the zero position can be programmed into the device. The absolute magnet angular position is measured with a resolution of 8 bit = 256 positions per revolution and is provided as a digital value on the serial interface (SSI) and on the PWM output signal.
