Fonctionnalités et applications

AMS designs, manufactures and markets high performance analog integrated circuits for communications, industrial, medical and automotive markets building on more than 25 years of analog design capabilities, system know-how, and own state-of-the-art manufacturing and test facilities.

AMS’ focuses on power management, sensors & sensor interfaces, portable audio and car access applications, and offers the industry's broadest range of high performance absolute and incremental rotary and linear magnetic encoder devices that are complete SoC solutions integrating Hall element, analog front end and digital signal processing.

The AS5045 is a contactless magnetic rotary encoder for accurate angular measurement over a full turn of 360°. 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 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 0.0879° = 4096 positions per revolution. This digital data is available as a serial bit stream and as a PWM signal.

An internal voltage regulator allows the AS5045 to operate at either 3.3 V or 5 V supplies


  • Industrial applications:
  • Contactless rotary position sensing
  • Robotics
  • Automotive applications:
  • Steering wheel position sensing
  • Gas pedal position sensing
  • Transmission gearbox encoder
  • Headlight position control
  • Power seat position indicator
  • Front panel rotary switches
  • Replacement of potentiometers

The AS5045 is available in a 16-pin SSOP package and has a wide temperate range of -40°C to + 125°C.
