1. Functional Diagram
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.

Output
Chopper
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.
