일반 설명

The AS5171 is a high-resolution angular position sensor for precise absolute angle measurement. The AS5171 is available with an analog output interface (AS5171A) or a digital output interface (AS5171B).
The AS5171A and AS5171B are available in a SIP package (system in package). The package has integrated the AS5171 sensor die together with the decoupling capacitors necessary to pass system level ESD and EMC requirements. No additional components and PCB on the sensor side is needed. The product is defined as SEooC (Safety Element out of Context) according to ISO26262.

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.
