Tle 5011: gmr-Based Angular Sensor
The Tle 5011 is a 360° angle sensor, which detects the orientation of a magnetic field.
This is achieved by measuring sine and cosine angle components with monolithic
integrated giant magneto resistance elements (igmr). The data communication 
is accomplished via a bi-directional Synchronous Serial communication (SSc) 
interface that is SPi compatible.
