일반 설명
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 5V or 3.3V.
The AS5116A is a preprogrammed version of AS5116. It has fixed settings and need no further programming.
With two decades of magnetic sensor system know-how, we have broad experience in selecting the most suitable magnets. ams experts recommend the following magnet suppliers.

Socket Board for AS5116
AS5116 Socket Board
The AS5116-SO_EK_SB socket board is used for quick programming of the AS5116 magnetic rotary position sensors without soldering due to its ZIF socket. This board is used in combination with the USB I&P Box or the SD4Y production programmer.
The PCB offers 2 connecting options: The 5-pin dual-row connector on the left side for connecting to the USB I&P Box and the 10-pin dual-row connector on the right side for connecting to the SD4Y Production Programmer. Furthermore, 8-pin header on top gives access to analog signals and GND signals. A ZIF Open-Top-Socket for SOIC8 packages is mounted in the middle. Pin 1 of the IC is indicated by a small dot on the left bottom corner of the socket or by the label on the PCB.
All passive components needed for proper operation are included on the PCB. Only a power supply mode of 5 V is possible.
Adapter Board for AS5116
AS5116 Adapter Board
The AS5116 Adapter Board is a small PCB allowing simple and quick testing or evaluation of the AS5116 magnetic position sensor without the need to build a test fixture or design an own PCB. The PCB can be connected either to an external microcontroller or to the USB
I&P Box.
The connector, 2x5 pin header (not populated), is included to this kit and is required for power supply as well as UART and analog interface.
