A19571 GMR Transmission Speed and Direction Sensor

The A19571 is a magnetic sensor integrated circuit (IC) that uses giant magnetoresistance (GMR) technology to encode the speed and direction of rotating ring magnets. Using a state-ofthe-art GMR stack design integrated with a BiCMOS process, the IC differentially measures magnetic fields and applies.

A19571 Features

* GMR technology delivers high magnetic sensitivity for large air gaps and minimal jitter

* SolidSpeed Digital Architecture provides robust, adaptive performance with advanced algorithms that provide vibration immunity over the full target pitch

* Flexible orientation allows
