12-bit magnetic rotary encoder IC
12 November 2008, Switches, Relays & Keypads

austriamicrosystems has expanded its magnetic rotary encoder portfolio with the 12-bit AS5145. The device is a contactless, complete system-on-chip for accurate angular measurement over a full turn of 360° with a resolution of 0,0879° = 4096 positions per revolution. This digital angle data is available using a simple serial interface or as a PWM signal. In addition, an incremental quadrature output mode with an improved interpolation algorithm can be enabled and permanently programmed with a resolution of 10 to 12 bits. Due to the higher noise performance the accuracy is thus further improved. Besides standard features such as user-specific zero programming, chip-ID and diagnostic functions for the correct positioning of the magnet, the AS5145 also provides a special feature to synchronise external electronics with itself, as well as a sine/cosine digital output mode.
