2. 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.

7. Applications Information
C1 and C2 values can be trimmed to satisfied EMC requirements according to the environment (PCB,
connectors,...).
The output rise time is affected for large capacitor C2, depending of the couple R1;C2.
Recommended Wiring

8. Installation Comments
1.) Avoid mechanical stress on leads or package.
Stress may cause V
oq
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
