综述

The AS5147 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 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 AS5147 and to program non-volatile settings without a dedicated programmer. The resolution of the ABI signal is programmable to 2048 steps / 512 pulses per revolution or 1024 steps / 256 pulses per revolution. The AS5147 has also a programmable UVW output and supports embedded self-diagnostics features.

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.
