1 General Description
The AS5132 is a contactless magnetic rotary encoder for accurate angular measurement over a full turn of 360 degrees. It is a systemon-chip, combining integrated Hall elements, analog frontend 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 absolute angle measurement provides instant indication of the magnet’s angular position with a resolution of 8.5 bit = 360 positions per revolution. This digital data is available as serial output over the interface and as a pulse width modulated (PWM) signal.
