Contactless position sensor

19 November 2014 Analogue, Mixed Signal, LSI

The new AS5601 contactless rotary position sensor from ams gives designers a reliable replacement for conventional rotary encoders, while providing a software-compatible incremental quadrature output. In devices which use rotary knobs, the Hall effect-based IC and its paired magnet can replace a rotary encoder without any change to the host microcontroller or its application software, and is also able to detect button presses. The device’s operation, including its zero position, provides for easy configuration, since its register settings are accessed via an I²C interface and are saved in on-chip OTP memory. The quadrature (A/B) output provides between 8 and 2048 positions, and users also have the choice of a 12-bit digital output.
