The AS5043 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 AS5043 provides a digital 10-bit as well as a programmable analog output that is directly proportional to the angle of a magnet, rotating over the chip.
The analog output can be configured in many ways, including user programmable angular range, adjustable output voltage range, voltage or current output, etc..
An internal voltage regulator allows operation of the AS5043 from 3.3V or 5.0V supplies.
The AS5043 is ideal for applications with an angular travel range from a few degrees up to a full turn of 360°, such as
