Infineon Technologies AS5048A and AS5048B are 14-bit rotary position sensors (previously known as encoders) for absolute angular measurement and with a pulse width modulation (PWM) output over a full turn of 360° based on contactless magnetic sensor technology. These devices fit perfectly on axis applications where a simple 2-pole magnet rotates above or below the sensor IC. The zero position can be programmed into the devices simply with a SPI (AS5048A) or I2C command (AS5048B). 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.
