    ... TLE4941C 41C0R The Hall Effect sensor IC TLE4941 is designed to provide information about rotational speed to modern vehicle dynamics control systems and ABS. The output has been designed as a two wire current interface. The sensor operates without external components and combines a fast power-up time with a low cut-off frequency. Excellent accuracy and sensitivity is specified for harsh automotive requirements as a wide temperature range, high ESD and EMC robustness ...

    ... The circuit is supplied internally voltage regulator. An on-chip oscillator serves as clock generator for the digital part of the circuit. TLE4941 signal path is comprised of a pair of hall probes, spaced at 2.5 mm, a differential amplifier including a noise-limiting low-pass filter and a comparator feeding a switched current output stage. In addition an offset cancellation feedback loop is provided by a signal-tracking A/D converter, a digital signal processor (DSP) and an offset cancellation D/A converter ...
