AMS OSRAM GROUP AS5048B-HTSP Magnetic Rotary Encoder, Programmable, I2C, 14 Bit , 3 to 5.5 V, -40 to 150 °C, SMD, TSSOP-14

AS5048B-HTSP is a magnetic rotary encoder. It is an easy to use 360° angle position sensor with a 14-bit high resolution output. The IC measures the absolute position of the magnet�s rotation angle and consists of Hall sensors, analogue digital converter and digital signal processing. The absolute position information of the magnet is directly accessible over a PWM output and can be read out over a standard SPI or a high speed I²C interface. It offers a PWM output, I²C interface. The zero position can be programmed via SPI or I²C command. This simplifies the assembly of the complete system because the zero position of the magnet does not need to be mechanically aligned. The sensor tolerates misalignment, air gap variations, temperature variations and as well external magnetic fields. Applications include robotic joint position detection, industrial motor position control, medical robots and fitness equipment.
