MLX90288
SMD Programmable Linear Hall Sensor IC
Featuring Analog Ratiometric Output
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.
