Description

The AS5116 is a contactless magnetic position sensor for accurate angular measurement over a full

mechanical turn of 360°.

Based on the Hall sensor technology, this device has a robust architecture that measures the

orthogonal component of the flux density (Bz), over a full-turn rotation. To measure the angle, only a

simple two-pole magnet rotating over the center of the package is required. The magnet can be placed

above or below the device.

The absolute angle measurement provides an instant indication of the magnet’s angular position. The

angle information is provided by means of buffered differential sine and cosine voltages. The AS5116

operates at a supply voltage of 5 V or 3.3 V.
