MLX90288 Datasheet 1. Features and Benefits 3. Description Surface mounted device The MLX90288 is a cost-effective monolithic Analog ratiometric output programmable linear Hall sensor which provides an analog ratiometric output signal proportional Measurement range from 6.5mT to to the magnetic flux density that is applied 650mT bipolar full scale perpendicular to the die surface. The MLX90288 is Digital IIR filtering for accurate bandwidth fully programmable (offset, sensitivity, clamping levels, magnet temperature drift, digital IIR Offset trimming possible outside output filtering ) through the connector, using the PTC- range 04 programming tool. It supports both linear and 1st and 2nd order magnet TC quadratic magnet TC compensation. compensation Reverse polarity and overvoltage protection Extensive diagnostic features Figure 1: gives the block diagram 2.
