The AS5040-SS-EK-DB is a magnetic rotary encoder module from ams. It is a single unit board which is suitable for consumer, industrial, and medical applications. The device provides a 10-bit resolution output, allowing angle measurements up to a resolution of 0.179 degrees. It supports a wide range of supply voltage between 2.7 V to 5.5 V, and can measure a full 360° range with a 0.179° resolution. The AS5040-SS-EK-DB also has an integrated velocity calculation circuit, which allows it to detect direction and count up to 255 RPM. The part is equipped with pin-configurable bus interface and provides step/direction outputs.
