... The peak detection concept also allows extremely low speed operation for small value filter capacitors. The ATS616 also includes self-calibration circuitry that is engaged at power on. The signal amplitude is measured, and then the device gain is normalized. In this manner switchpoint drift versus air gap is minimized, and excellent timing accuracy can be achieved ...

... Superior Performance. gear-tooth sensor module has several advantages over conven- tional Hall-effect gear-tooth sensors. The signal-processing techniques used in the ATS616 solve the catastrophic issues that affect the functionality of conventional digital gear-tooth sen- sors, such as the following: • Temperature drift. Changes in temperature do not greatly affect this device due to the stable amplifier design and the offset rejection circuitry ...
