ams – AS5047P: 14-Bit on Axis Magnetic Rotary Position Sensor


The AS5047P is a high-resolution rotary position sensor for high speed (up to 28krpm) angle measurement over a full 360° range. This new position sensor is equipped with revolutionary integrated dynamic angle error compensation (DAEC™) with almost 0 latency and offers a robust design that suppresses the influence of any homogenous external stray magnetic field. A standard 4-wire SPI serial interface allows a host microcontroller to read 14-bit absolute angle position data from the AS5047P and to program non-volatile settings without a dedicated programmer.
