TLE4997A8DXUMA1

TLE4997A8DXUMA1 is a programmable linear hall sensor. The linear hall IC TLE4997A8(D) 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 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. It is ideal for robust replacement of potentiometers: no mechanical abrasion, resistant to humidity, temperature, pollution and vibration. The linear and angular position sensing in automotive and industrial applications with highest accuracy requirements. Suitable for ASIL applications such as pedal position, throttle position and steering torque sensing.
