Functional Description

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.
