Error variations correcting circuit for hall sensor

摘要: PURPOSE:To obtain a Hall sensor suitable for wide range of use, by correcting error variations output generated due to non-magnetic field factor in terms circuitry avoid erroneous magnetic detection the based on component. CONSTITUTION:In so designed signal comparing voltage element 4 responding external with threshold voltage, higher +amV Min value 40 as reference is supplied VTH27, timed rise 26 from G input unit 23. Thus, it possible make processing comparator 8 correspond changes secular unbalanced 4.
