    Description

    The MLX90242 is a CMOS Linear Hall Effect sensor IC. It possesses active error
correction circuitry which virtually eliminates the offset errors normally associated
with analog Hall Effect devices.

    The ratiometric output voltage is proportional to the supply voltage. When using
the supply voltage as a reference for an A/D converter£¬fluctuations of +10% in
supply voltage will not affect accuracy. For a positive slope £¬ the voltage

    at the output will increase as a South magnetic field is applied to the branded
face of the

    MLX90242. Conversely£¬ the voltage output will decrease in the presence of a
North magnetic field. For a negative slope£¬ the voltage at the output will increase
as a North magnetic field is applied to the branded face of the MLX90242.

    Conversely£¬ the voltage output will decrease in the presence of a South magnetic
field

    Installation Comments

    1.£© Avoid mechanical stress on leads or package. Stress may cause Voq shift.
A.£© Avoid bending leads at the package interface. B. £© Support the leads by clamping£¬
when bending. C.£© Avoid gluing device to another material. This may cause temperature-related
stress. 2.£© CMOS products are static sensitive devices £¬ please observe ESD precautions.
3.£© Observe temperature limits during soldering
