资 源 简 介
The KMZ51 and KMZ52 from Philips Semiconductors are magnetic field sensors, dedicated to compassapplications. Both sensors rely on the magnetoresistive effect and provide the required sensitivity and linearityto measure the weak magnetic field of the earth. While the KMZ51 is a single axis field sensor, the KMZ52comprises a two-dimensional field sensor, as it is required for a compass, within one package. Both devices areequipped with integrated set/reset and compensation coils. These coils allow to apply the flipping technique foroffset cancellation and the electro-magnetic feedback technique for elimination of the sensitivity drift withtemperature.
