HallLinear Analog REDUNDANT Description
The linear Hall IC TLE4997A8D has been specifically designed for highly accurate angle and position detection. 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 together with digital temperature and analog stress compensation guarantees excellent stability over the whole temperature range and life time.
