资 源 简 介

The KMZ51 and KMZ52 from Philips Semiconductors are magnetic field sensors, dedicated to compass applications. Both sensors rely on the magnetoresistive effect and provide the required sensitivity and linearity to measure the weak magnetic field of the earth. While the KMZ51 is a single axis field sensor, the KMZ52 comprises a two-dimensional field sensor, as it is required for a compass, within one package. Both devices are equipped with integrated set/reset and compensation coils. These coils allow to apply the flipping technique for offset cancellation and the electro-magnetic feedback technique for elimination of the sensitivity drift with temperature.
