... General Information TLE4926C is an active Hall sensor suited to detect the motion and position of ferromagnetic and permanent magnet structures. An additional self-calibration module has been implemented to achieve optimum accuracy during normal running operation. It comes in a three-pin package for the supply voltage and an open drain output ...

... Figure 2: Block Diagram of TLE4926C Basics of self-calibration A magnetic signal generated by a typical toothed wheel looks somewhat like a sinusoid. Optimum switching points lie near the zero crossings of the curve. Due to backbiasing conditions and imperfections in the IC the signal is superposed by an offset ...
