3 General Description

The MLX90288 is a cost-effective monolithic programmable linear Hall sensor which provides an analog

ratiometric output signal proportional to the magnetic flux density that is applied perpendicular to the die

surface. The MLX90288 is fully programmable (offset, sensitivity, clamping levels, magnet temperature drift,

digital IIR filtering …) through the connector, using the PTC-04 programming tool. It supports both linear and

quadratic magnet TC compensation.
