AS5145H/AS5145A/ AS5145B
12-Bit Programmable Magnetic Rotary Encoder
The AS5145 is a contactless magnetic rotary encoder for accurate angular measurement over a full turn of 360 degrees. It is a system-on-chip, combining integrated Hall elements, analog front end and digital signal processing in a single device. To measure the angle, only a simple two-pole magnet, rotating over the center of the chip, is required. The magnet can be placed above or below the IC. The absolute angle measurement provides instant indication of the magnet’s angular position with a resolution of 0.
