TLE4997A8DE0300XUMA1

The linear Hall IC TLE4997A8D Grade1 has been designed specifically to meet the requirements of highly accurate angle and position detection, as well as for current measurement applications. The The sensor provides a radiometric 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. The minimum overall resolution is 12 bits. Nevertheless, some internal stages work with resolutions up to 20 bits.
