ams: AS5147P: High Speed Rotary Position Sensor for Safety-Critical Automotive Applications

AC_ams_PP_AS5147P_CMYKams-logo
The AS5147P 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 a revolutionary integrated dynamic angle error compensation (DAEC™) with almost zero latency. The robust design of the device 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 AS5147P and to program non-volatile settings without a dedicated programmer.
