General Description

The AS5047D is a high-resolution rotary position sensor for fast absolute angle measurement over a full 360-degree 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 AS5047D and to program non-volatile settings without a dedicated programmer. The resolution of the incremental ABI interface is programmable with a maximum resolution of 2000 steps / 500 pulses per revolution in decimal mode and 2048 steps / 512 pules per revolution in binary mode.

Magnets cannot be ordered at ams directly. Please find a list of recommended magnet suppliers.
