The linear Hall IC TLE4997I has 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 for A/D
conversion with the supply voltage as a reference.
The IC is produced in BiCMOS technology with high voltage capability and also providing
reverse polarity protection.
Digital signal processing using a 16 bit DSP architecture and digital temperature
compensation guarantee an excellent long-time stability.
The minimum overall resolution is 12 bits. Nevertheless some internal stages work with
resolutions up to 20 bits.
