General Description
The AS5046 is a contactless magnetic angle encoder for accurate measurement up to 360°.
It is a system-on-chip, combining integrated Hall elements, analog front end and digital signal processing in a single device.
The AS5046 provides a digital serial 12-bit as well as a programmable 10-bit ratiometric analog output that is directly proportional to the angle of a magnet, rotating over the chip.
In addition, the serial interface enables a user configurable arrangement of the Hall array and allows access to each individual Sensor of the Hall Array.

Key Features
• 360° contactless high resolution angular position encoding
• User programmable zero position
