AS5047 Rotary Position Sensor Slide 5

The challenge with existing magnetic position sensors on the market is a delay which comes by nature of the signal processing. This leads to incorrect angle position outputs, especially at high rotation speeds. The value of the dynamic angle error depends on rotation speed. Additional hardware components can calculate this error and make a software correction on the output angle, requiring a large software development. This result is not as accurate as the DAEC™ from ams OSRAM. The DAEC™ Dynamic Angle Error Compensation is the unique feature of ams OSRAM's new generation of magnetic position sensors. It is a single chip solution which reduces the dynamic angle error nearly to zero. It delivers all the advantages of contactless angle measurement and provides better accuracy over speed. Overall, it is easy to use, simple to program, and reduces development costs as well as time to market.
