The 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.
