ams OSRAM AS5070
High-resolution on-axis magnetic angular position sensor
The AS5070 is a high-resolution angular position sensor for precise absolute angle measurement - available with an analog output interface (AS5070A) or a digital output interface (AS5070B). The latter can be programmed as a PWM or a SENT-compliant output interface.
Based on a Hall sensor technology, this device measures the orthogonal component of the flux density (Bz) over a full-turn rotation and compensates for external stray magnetic fields with a robust architecture based on a 14-bit sensor array and analog front-end (AFE).
