XENSIV™ - TLE4997E linear Hall sensor for highly accurate rotation and position detection

The Infineon linear Hall IC TLE4997has been designed specifically to meet the demands of highly accurate rotation and position detection, as well as for current measurement applications. The sensor provides a ratiometric analog output voltage, which is ideally suited to Analog-to-Digital (A/D) conversion with the supply voltage as a reference. The IC is produced in BiCMOS technology with high voltage capability and also provides reverse polarity protection. Digital signal processing using a 16-bit DSP architecture and digital temperature compensation guarantees excellent stability over a long period of time. The minimum overall resolution is 12 bits. Nevertheless, some internal stages work with resolutions up to 20 bits.
