综述

The AS5147P is a high-resolution rotary position sensor for high speed (up to 28krpm) angle measurement over a full 360 degree range. This new position sensor is equipped with a revolutionary integrated dynamic angle error compensation (DAEC™) with almost 0 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.
Incremental movements are indicated on a set of ABI signals with a maximum resolution of 4096 steps / 1024 pulses per revolution. The product is defined as SEooC (Safety Element out of Context) according ISO26262 including FMEDA, safety manual and third party qualification.

With two decades of magnetic sensor system know-how, we have broad experience in selecting the most suitable magnets. ams experts recommend the following magnet suppliers.
