AS5040-ASST

AS5040-ASST is a 10Bit, contactless magnetic rotary encoder for accurate angular measurement over a full turn of 360°. It is system-on-chip, combining integrated Hall elements, analogue front end, and digital signal processing in a single device. To measure the angle, only a simple two-pole magnet, rotating over the centre of the chip, is required. Magnet may be placed above or below the IC. The absolute angle measurement provides instant indication of the magnet’s angular position with a resolution of 0.35° = 1024 positions per revolution. Applications include contactless rotary position sensing, robotics, brushless DC motor commutation, power tools (industrial applications), steering wheel position sensing, gas pedal position sensing, transmission gearbox encoder, headlight position control, power seat position indicator, office equipment: printers, scanners, copiers, replacement of optical encoders, front panel rotary switches, replacement of potentiometers (automotive).
