General Description
The MLX90251 is a CMOS Programmable, Ratiometric Linear Hall Effect sensor IC. The linear output voltage is proportional to the magnetic flux density. The ratiometric output voltage is proportional to the supply voltage. The MLX90251 possesses active error correction circuitry, which virtually eliminates the offset errors normally associated with analog Hall Effect devices. All the parameters of the MLX90251 transfer characteristic are fully programmable.
