AS5048B Rotary Position Sensor

14-Bit Rotary Position Sensor with Digital Angle (interface) and PWM Output

The AS5048B is a 14-bit rotary position sensor (previously known as encoder) for absolute angular measurement and with a PWM (=pulse width modulation) output 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 simply with a I2C command. The absolute magnet angular position is measured with a resolution of 14 bit = 16384 positions per revolution and it is provided as a digital value on the serial interface (I2C).
